I love my iPad so much I never felt the need to upgrade to 4.2, now with an app that only works on 4.2 I think it's time. How do you guys like your iPads on 4.2? Are they just as fast? Any negatives? Battery life?
4.2 works awesome - No problems at all. In fact, I found performance improved. If you are worried that 4.3 might have issues, update to 4.2 today and wait and see how Ipad 1 users react to 4.3. Honestly, I'll bet 4.3 works great as well. With IOS products, you usually get 1-2 upgrades before things get slow. (E.g think Iphone 3g issues on 4.1)
