Personally I prefer beer and pizza rolls when I'm playing my whiny prima-donna characters.
I'm giving 4ed the cold shoulder for now. I've just put too much into 3.5 to start up with a whole new system. My friend that usually DMs for us has bought WAAAAAY too many 3.5 books and it would be a waste of money for him if we changed up.
Besides, I just taught my 13 year-old cousin to play 3.5 a few months ago. He loves the game, but it will really confuse him if I switch systems on him now.
Don't get me wrong, I know myself well. In a few months I'll pick it up, or someone will suggest we give it a try, and I'll love it. Then I'll be buying the new books... That's why I have some books from each of the editions in my collection.
