Windows Tablets versus Android and iOS.
Unfortunately Windows 7 and likely W8 have high background activity and while that may be a plus in a corporate environment, it is likely not a plus to a home computer user. I have a ASUS Netbook that came with Windows 7 Starter and I have upgraded to Windows 7 Home Premium and also added an additional gig of ram to make it two gig. I also have an Intel N550 Atom processor that effectively has 4 cores, and even with that supposedly impressive array, using the Netbook can seem like driving a Model T up Pike's Peak. I installed Android 4.0.3 ICS on it, and it is a lot more speedy, and effectively is a lot more enjoyable to use with ICS than W7. There are just too many background services going on with W7, and probably most of them are not important to a home user, but you can be reticent to disable them.
I have 2 i 7 computers, a desktop and a laptop for when I want and need them, but my next purchase will be an Android Tablet, likely an ASUS TF700 rather than a W8 machine. I like the speed and ease of Tablet use and will give it a shot. After my experience with Android on my Netbook, I am looking forward to getting a more polished version of the O/S in an ASUS tablet. Within 6 months, my Netbook will likely be history and will be using my tablet frequently for things that don't require a heavy duty computer. The resources of an underpowered computer will be just fine for an Android Tablet. It is hard to tell what lies ahead with computers, but time will tell if Windows types will be abandoned by home users for more convenient Tablets. You can hook up a keyboard and mouse to them and also use an external Monitor and have a nice set up. By 2017 we should have a better feel about where the computer market is going long term.
