Did not see a thread on this so do you have the iPad 1 or iPad 2? I have iPad 1 and am satisfied! The 2 was not a big enough upgrade for me.
I have an iPad 1, and I didn't think that there was a compelling reason to upgrade to an iPad 2. But if I didn't have an iPad, I wouldn't even think about buying the first one. I'm still happy with the iPad 1 though.
I have both and love them both, both do what I want very well.
