So I Installed Vista Yesterday...

I installed Vista yesterday, and I was wondering if anyone else had it installed and what they thought about it. I really like it, I think it's a nice upgrade from XP. It's not as much of a memory hog as I've heard, it looks great, and everything runs very smoothly. The new sidebar, photo gallery, dvd maker and upgraded media center are great and immediately usable to me. I haven't had any problem installing any of my old programs with the exception of Nero 7, which doesn't support Vista (but I can write dvd's from Vista now anyway). My only beef as of now is that it doesn't seem to let you run unsigned (or unapproved I guess) programs at startup. I have a feeling there's a setting somewhere to change that, but I haven't found it. So for now I have to tell it to start the one program that doesn't at startup. Anyway, let me know what you guys think.
