before i am going to get it I want to know what the "few stumbles back" are. I don't want to buy the "new and improved" only to find out it has taken away features that are important to me. example: imovie.
I understand your iMovie quote. You mean when you installed iMovie 08 and it removed your iMovie HD without telling you.
Well you have all your guessers changed and scrolling, but you can change those back. You will lose front row and your ability to customize the finder's sidebar. All your devices will be at the bottom which is annoying. iMovie '11 right now constantly crashes on me, so I'd wait if you use that a lot... that's all I've noticed.
