- For a tablet of this size, don't you expect to have handwriting recognition? Hey but iPad has a capacitive touch screen so that probably will not work.
- Does it have palm rejection? No one seems to say anything about this.
- Then there are a whole lot of other things: no multi-task, no web cam etc. etc. that many others have pointed out as obvious omission.
For me the Asus T91MT, that I have been using has all of this. Though it is not all good with palm rejection; it only works well with Microsoft Journal. I heavily depend on the Windows 7 handwriting recognition and has become my primary means of entering notes or writing lots of text; it just works for me. And it has a inbuilt physical keypad, in case you need one (write code?!). I have not yet tried programming on T91MT, but would do so soon ;-)
In any case it depends what you are looking for: if you want a fine balance between productivity and entertainment go for a tablet like Asus T91MT which has an integrated physical keypad. If you are looking for mostly an entertainment centric and content consumption device with which you would also like to get some productivity you might think of getting an iPad. Both of these, I guess, cost almost the same.
