When I first bought the unit, it was the one to have (in my mind) if you did not want a Blackberry. The keyboard on the Cingular sister unit was better, but I wasn't going to switch service for that. It had all the bells and whistles, and certainly earned its "PocketPC" title. It came with all of the Mobile MS software, which I thought would be very useful, but didn't turn out to be very easy to use. It also had built-in Wi-Fi and bluetooth, but I found the IE browser to be a little troublesome (imagine that).
Overall, the unit proved to be reliable, but I have to say that the thing I like the least was the touch keypad for the phone. I cursed seven devils every time I had to use it. It's saving grace was the voice dial, which I used often, and was really quite reliable compared to my current Blackberry.
As a whole, I believe that the downfall of the devices such as the T-Mobile MDA, its twin the Vario, the Cingular 8125, and others like it, had to be that accursed touchpad.
New units such as the Instinct from sprint seem to have addressed that problem with a tactile touchscreen. Sprint has a very cool promotion for the Instinct on its website.
The T-Mobile MDA and its bretheren, were originally engineered by the Taiwanese company, HTC. They also designed the iPAQ, back in the day, and its similarities can been seen in the Wizard-type units such as these.
Our specimen has a Texas Instruments OMAP850 195Mhz cpu, 64Mram ( 45 available after the OS ), a 2.8' QVGA display - 65k colors, and stereo sound ( very good stereo when using headphones), 1.3 Mp camera, and WindowsMobile 5.0. Some have upgraded theirs to a modified version of 6.0, which I may do now that it is not the center of my cellphone life.
Well - on with with it - Lets Crack it open!
The large screen is what I ( and many others I expect) liked about these units.
