Well have been using the iPad 1 for some time now, 2 years almost I would guess , give or take a couple of months. It has effectively replaced my laptop. It does most of what I need, send emails, check info on the web, download files, annotate , etc. it does most everything.

It's fast, and is super convenient. Battery life is another plus. I'd say best device in its class. The trick is that what it does it does extremely well. I also read books on it, play the occasional game and it hasn't let me down once. Push the start button, and presto, it's ready to go. Brilliantly conceived , that's the genius of Jobs I guess.
