Well, I'll reply to walt526... the eDGe UI does take some getting used to (I'm a long time Mac user), but this device has way more functionality than anything like it on the market right now (we're talking the mobility market). It IS outstanding. It IS worth the learning curve. It does WAY more than iPad and Kindle, to date. You might want to look into it. If you are into 'function' (not media and social stuff, so much... it does do that, too... and will do increasingly more, I'm sure, in the near future), but in terms of functionality and 'work', this IS the leader, right now. It is definitely worth a look. While this product is being directed to students, it is becoming apparent that it is hitting with people in, not only, the education area, but also, with people in sciences, r&d, and many other work related areas, etc. For instance, MD's, research scientists, research 'anyone' (*), and personal users who have a bent for study and research. It is the awesome tool because you can read on one side and do your research and/or take your notes on the the other. There is a lot of flexibility here.
TAKE NOTE.
