This thread actually died for a long time, mainly due to Android tablets either being complete crap (1.6 or 2.0) or just vapourware.
Now that a year has passed and a few alternatives have started to creep into the market, it is generating a bit of interest.
I like the Viewsonic because I like the idea of the consumer side apps of Android and the work crap I have to carry that lives on Windows residing in the same box.
I wasn't paying much attention to MWC, but there are new tablets from Samsung, HTC, and Toshiba in addition to the ASUS.
HTC Flyer
Toshiba 10.1"
Samsung Galaxy Tab 10.1"
Toshiba 11"
The EP121 looks good, but what's the realistic battery life?
