Hi Guys, Can you show me where is this playbook WiFi antenna located at motherboard? Is it the black wire located at the right top which we can see also others 3 antenna? Kindly revert asap. TQ guys.
The L883 2048 chip is a HMC5883L 3-Axis Digital Compass IC. See: http://www.dsscircuits.com/articles/the-mysterious-hmc5883l.html
iPad, Playbook - OSX, Win7, Android. The reason why there are so many choices is because people have opinions and different preferences on everything. Each device owned by someone, is the best ever! I own a BB; and I am going to buy the Playbook. I am just a BB fan. My neighbor has an iPad; does that make him my enemy. Grow up people.
I have a number of ones you could try. How about " OVERMYHEAD" or this ones more in line. " OVERDONE " My last one is a winner " OVERTOYOU " If you google "computer sales leader " What company's name pops up the most. APPLE ! By the way, Samsung is a fantastic company, they make good photocopiers, so you can say there experts in making copies. On last point. The manufacturing of any type of electronic product now requires help from all companies. But does it give them the right to come into your country and steal from your peoples ideas. (Jobs) Do you really think thats " OK" Mr. OVERK1ll? Whats your answer!
In 4 months you would see hundreds of other computer manufactures with computers that look a car. If Apple was to design a computer that hovers 5 feet of the ground, in 4 months we would be covered in floating LG, Samsung, RIM and Dell computers. Get my point! There is only one leader of the pack so get over it.
they are once again trying to sue for the look and feel which they lost last time. How the hell can you say you have a patent for 4 icons across that is ludicrous and the patent after this case will be revoked as it should never have been granted. Everyonce can see that apple has not come up with 'one more thing' this time. There device is inferior and in no way a PC replacement as is being touted mainly due to the fact that you still need a PC to connect to in order to activate your device and also to transfer files to and fro. Tablets are meant to be interfaces to the 'cloud' not a conduit between desktop and the cloud.
If Apple can sues samsung and the galaxy tab for copy infringement, the RIM will be next. This is one very cool "Apple Like" Tab, much better then Samsung, but a lot more " Apple " influenced in the programing. The screen layout, Text & user interface is more Mac like. In the end, after everyone gets their day in court, Apple will get "IP royalties" from both samsung & RIM. Then Apple will move on and make more money every-time someone buys a PayBook or Tab. Just like it did from Microsoft. ( check your history books for that one) http://www.computerworld.com/s/article/9215920/Apple_sues_Samsung_says_it_copied_iPad?taxonomyId=12
We've had a few iPad's at the office, but they failed to provide the same "Outlook Experience" that users got with their Blackberry devices. The gripe of course being that they want to see their calendar and other related PIM information on a large screen, while being able to access websites and the like. This can, and is all done on the Playbook. And done WELL. Exchange integration through the Blackberry bridge is fantastic. The bridge browser can be used to securely access internal websites, I can use it to check on routers, login to the AP's, check toner on the printers....etc. It just "works" in a lot of areas of enterprise that the iPad doesn't. However the iPad has a lot of apps. And if you just love to have apps.... Then I guess it has that going for it.
I was at a my local London Drugs store (Vancouver) yesterday and talked to a BB user that was going to purchase the new PB. - He had a hate going on for all things Apple. He said that he had to buy the PB because of that fact. He also said that the iPad 2 had more to offer then the PlayBook, but due to the fact that it was made by Apple, he had to settle for the PayBook. Logical. Maybe not. It looks like RIM may get some buyers with that type of mindset. Apple Haters ! lol
Before cracking open the BlackBerry PlayBook, I gave it a little test drive. I wouldn't call my experience a complete road test, but the device seemed sturdy, ran well, and had some nice features--great screen, good cameras, and Flash support. Check out Jason Hiner's first look at the PlayBook for more details: http://www.techrepublic.com/blog/hiner/blackberry-playbook-first-impressions-four-pleasant-surprises/8143 Yet, I was still left with the impression that RIM's tablet won't have much success with companies or individuals that aren't existing BlackBerry customers. What do you think?
Im sure there is alot of discussion on the IPAD in reference to a teardown or any topic of discussion with regard to Apple, Apple is the Mercedes Benz of Computing Hardware inside and out why do we need knock offs ?
Obviously you didn't read the story of the manufacturing plant in CHINA where they strung up nets to keep the workers from jumping from the roof because of such poor working environment and pay equivalent to $2/hr making iPad parts. Apple is as low as they can get. I wouldn't buy anything from them on that premise alone. You are blinded by a Name.
If Apple was so "American" they wouldn't be making all their stuff in China now would they? Stealing jobs? Yeah, that would hold water if their products were manufactured in North America. But they aren't. BTW, fantastic debating skills sir. Skip the facts (Apple is a "designer", they don't actually MAKE much of anything and subsequently buy from and have products produced by Samsung, Intel, Foxconn....etc.) and just go for the insults and hope nobody notices. Apple is suing one of the companies they contract to produce parts for their products. If you've ever heard the old proverb "don't crap where you eat", it applies here. Regarding sales: Dell for example, employs twice as many people as Apple (103,300 vs 49,400). But Dell uses the same suppliers (Samsung, Intel, Foxconn....etc) as Apple. So using your convoluted logic, that makes them twice as "American" as Apple..... And that's without mentioning HP, who employs 324,600 people. Regarding computer sales: In 2010 there were 346.2 million PC's shipped. The top three manufacturers were HP: 18.8%, Acer: 12.7%, Dell: 11.6%. Apple isn't even on the list. If we focus on the US only, the ranks fall as: HP, Dell, Acer, Toshiba, Apple. So instead of googling "computer sales leader", I went and provided you with the actual numbers. Which in no way support what you are saying. Apple isn't the computer sales leader. They aren't even close in their home market, and not even on the radar globally.
According to that logic, everyone should have made a phone with an antenna that failed when you touched it. Give It A Rest!
Really? I thought Apple just sold other people's hardware, manufactured in the same facilities (Foxconn for example) as everybody else? Who manufactured/developed the CPU in the iPad/iPhone again? Samsung? Who does Apple use for CPU's now? Intel? Motherboards? Foxconn. Apple is shepherd. A shepherd is only your leader if you are a sheep.
as is the recent troll trend, but they usually lose (they have worse track-record than MS at this type of tactic!). Given that many of the core ideas embedded in iOS - which stemmed from OS X - were in their own turn "influenced" by others, the whole thing is a joke. This is where patent laws need a serious overhaul to stop this kind of nonsense... technology evolves, and nothing evolves in sterile jars. Every "invention" in the techo-world is spawned from earlier ideas, both in terms of strengths and weaknesses. Given that the iPad wasn't even the first tablet computer, nor did Apple create the first touch-interface OS, maybe someone should sue them for stealing THEIR innovation... it would be just as stupid!
And Apple charged with damages and court costs, because that is a really stupid lawsuit. We should sue Coby for using the same font as Sony... LG should sue Sony for copying its TV colour pixels. I really hope for the day Apple crashes and burns again. They deserve it.
Again, separate your identity from Apple and chill! One of the main reasons there are so many "haters" has little to do with their products, but a lot to do with the attitudes of their fans... attitudes carefully cultivated by the Apple Corp. Even devoted users of most tech company's products still don't either have a blind devotion or identities tied-up with a brand name... we can happily admit when (or gnash teeth) our favourite tech company gets it wrong. Apple devotees however seem unable to admit when Apple either falls short or even brazenly screws up, and get all offended at any criticisms laid at the alter of Jobs! Seriously kid, grow up!
What nonsense. Macs are consumer items and contain the same parts as any other PC. And they are made in the same factories. There is nothing better about them and, when it comes to business grade laptops, they are positively inferior as part specs change unpredictablyon the same sku and at a dizzying rate. Have you ever looked inside an HP or Dell server. That qualifies as first-rate: quality parts, beautiful construction, fine engineering. Consumer products are consumer products are consumer products differentiated mostly by marketing fluff for which Apple fans seem to have a weakness.
Apple may be the Mercedes Benz of Computing, but Audi, BMW, and Jaguar have their 'versions' too... in some ways superior, in some ways inferior. In either case, choice is good for consumers.
Maybe for the same reason Apple made their 1984 commercial. People want and should have choice without a big brother to decide. Not everyone wants a Mercedes either. Also, there is no such word as alot it is a lot.
Like most people, I put my phone in a nice little case, so a never had a problem. As Apple pointed out a lot of phones have the same problem. It was never a big deal for most. Just a few iHaters had the problem, of course they don't have the IQ to buy a case, so there you go.
As a Mac/PC Tech (retired) I have worked on a large number of computers - from Mac to HP, Dell, Acer, you name it! I can tell you without any questions that Apple may use parts that are the same in other computers, but the construction & engineering is always top drawer. I can say that I have seen other companies cut corners and make things very difficult to repair. I'm not saying that Apple is perfect, but they are at the top of the heap, Acer on the other hand is at the bottom. But thats only my humble opinion, and with 35 years in this business I hope it counts. As for Consumer products , they are the best of the best.
Not sure where you get your information, but no, the Blackjack wasn't a Skype device. It's a GSM quad-band and UMTS dual-band device, one of the first to use simultaneous voice/HSDPA technology for high-speed data transmission on the then fairly new AT&T 3G network.
Thanks Fritzpk for the background info FYI - The Blackjack is a "Skype" type device. It works on VoLP. Vonage, the company that pioneered the use of VoIP. Now, companies are developing ways to allow people to use voIP on popular smart phones such as the Motorola Q and the Samsung Blackjack.
And the Blackjack that I kept instead of buying the first iPhone got handed down through 3 people. Ironic thing is that the phone never had to be hooked up to a charger. It would blast through 3G all day long. It came with a backup battery and a charger for it. I also used it as a tethered modem for my laptop. I could look at the complete file system on my laptop just like another drive. I could drag and drop anything anywhere. I could load my own music and make my own ringtones. I didn't need a credit card to buy it and I didn't have to put up with iTunes or Apple being up my ass with all their rules and regulations and bricking. The numbers you use sound impressive but only represent .2 percent of the worlds population, and I'm not surprised there's that many lemmings around. You may not want to brag to loud about being one. Oh, and yes the Blackjack still works, original batteries and all. If you need a phone I'll sell it to ya cheep.
Yes, my iPhone 4 is getting a little long in the tooth. Its almost 2 years old and a little out dated. I got a 3G with the new iPhone 3.0 iOS from Rogers Wireless on June 19, 2009, Then I upgraded it to a 4 in July of 2011. As soon as the iPhone 5 is released this fall, I will pick up 32 GB unit. I really don't what to brag about it Frispk , but that thought that you be interested. Oh, about that battery situation, I gave my old 3G to my son, when I got my G4 and it's working just fine that you. Thats 3.5 years and it just keeps ticking. On the other had, my daughter has gone through 3 BB and now she's on to a some droid, and she hates it, and will get a iPhone next time. She said that she has learnt her lesson. She must have drank the from the same tap that you do. lol Anyway I have wasted my coffee brake typing this out so I got to go now, have a good day in your land of the bewildered.
That's an awful lot o' people with rings in their noses. There was a story about something like that and lemmings. You got nothing to brag about except not being able to think for yourself.
You're just another fanboi with your eye's closed. Your logic comes from having to defend defective products. Smart people don't have to take defensive positions like that. Never bought an iPhone....Never will. Never bought an Apple product....Never will. I bet you have one of every iPhone...maybe more. I looked at the first iPhone and thought 'What kind of an iDiot would buy something when you can't change the battery?' Never bought an iPhone....Never will. Never bought an Apple product....Never will. I bet you have one of every iPhone...maybe more.
Seriously mate, you need to detach your identity from the glowing Apple and stop taking any criticisms of Apple Corp so personally! Apple may make some good product (hell, even Akai, Teac, Acer can say the same), but they also make a lot of over-priced JUNK (and this is coming from an ex-fanboi!) iPhones... innovative, pretty, but ultimately over-rated. Sells on a combination of cool-factor and apps. Those who REALLY need a smart phone are still slow adopters. Oh, and don't even start on sales stats, which pitch a single phone model against competitor who make a RANGE of phones! And given the alarming number of iPhones I see with cracked screens, that doesn't scream quality! iPods.... apart from the same screen issue in common with the iPhone, even my Apple-lovin' friends admit that iPods are cr@p. The wheel on iPod classic's has a habit of barely outlasting the warranty, it requires iTunes (the WORST media application on the planet!) and still has audio fidelity comparable to those Korean mp3 players found in your average $2 shops! AppleTV... not bad, just simply not comparable to the range of options available. Macbook Air... pretty, gimped, lightweight both in terms of actual weight and hardware features! iPad(1 & 2).... in addition to the Air, it has a gimped OS that is fine for the GenY'er who just can't bear to be away from Facebook for 2 seconds, but (and yes I know there is a half-useless App to sorta fix this) doesn't actually need to do any REAL work (ie, content creation). Not just a crit of Apple on this; still waiting for a tablet computer (in ANY OS) designed for the professional who needs a serious workhorse in tablet form... all seem to be aiming at the low-brow market at present! "One last point, if you're not an engineer or service technician, why are you posting stuff that can't be backed up with stats or training." Stats are not only of limited relevance in a specified context, they are easily manipulated and thus the tools of the manipulator or the fool!
How many people have purchased a cell phone , used it for 3 years (term of the contract) then replaced it with a new phone? Millions Right! Ok, now how many of those same people replaced the Battery in the phone. About 2% or less. Its that same thing with a digital camera. - Apple know this. If you seal off the battery case that unit is a bit more water tight. Less problems. If the Battery was to malfunction in less then a year, its under warranty, so Apple will replace it for free. New batteries, cduance are made to out last the product they are installed it. Now you know something any 10 year old would understand. On the other hand, if you keep old Apple products like I do, just as collectables, there is tons of websites that show you how to replace batteries in all of Apples products. One last point, if you're not an engineer or service technician, why are you posting stuff that can't be backed up with stats or training. Just to repeat what other have said doest make you an expert.
apple products have always been throw away items they want you to buy a new one and not repair your old so they actually do make it more difficult than it needs to be. Why else would they not have removable batteries in small devices?
For you young whippersnappers, "the business" in 1976 included mainframes and a few of the "new PCs" of that era. I was also "in the business" back then. I know and understand what he's talking about. If I had to have a system worked on today, I'd much rather have someone of his experience touch my system than one of the newbies that don't understand how things work under the hood (hardware, OS, & networks). Show some respect. You don't know him from Adam.
