I've got a 3, I love it, and I probably won't upgrade anytime soon. I don't know who was complaining when it came out, or what they were complaining about, but I have had a great experience with it from day 1.
That said, if I didn't have the 3 and was going to buy something now, I'd definitely get the 4. I cannot see the value in spending hundreds of dollars for a piece of outdated tech, when just a few dollars more would get me the newest version.
It doesn't matter if you are playing games or not, the faster the better, in my opinion. I read a lot of PDFs on the iPad, and even an extra 1 second per page load (large files of scanned books take a while to render sometimes) would be greatly appreciated.
