Not me.
I had been waiting for the better iPad 3. My wife was eager to get an iPad 2 in the fall, but I said let's wait.
Well, I won a work Costume contest and got myself/us an iPad2.
So, I am waiting until the next release.
I had thought about selling it and then buying the next version: iPad3.
And seeing as it was "all profit" I wouldn't feel horrible. BUT, then I thought about it, my iPad 2 works for us right now. Waiting another year, I can have the top digs then, and rather than sell it, just pass it along to my son, or perhaps parents to use.
