It would be hard for me to use the new iPad more than my previous one, because I used the gen 2 every day - in fact I have rarely been without my iPad since buying gen 1.
I would say I use the new one just as often, and enjoy it more because of the new features. But I agree that there's really no need to buy every new version, and not realistic to expect a huge wow factor annually. I did buy each new iPad so far, because I use it lot, but I also consider it a splurge to do so, not a necessity.
Exactly. Given my usage it's not physically possible to use the new more than the 2!
And I came to the same conclusion - given my usage the upgrade was a no brainer but for most sticking with the iPad 2 is completely fine.
