Should I install Windows 7?

As of right now, im running just ubuntu. I misses my my games :( so i think im going to be throwing windows on my other hard drive. Question is, do I install windows 7 or just go back to XP?

I’ve read mostly positive reviews for 7 but well i read some great reviews for vista too soooo i dont put too much weight in that kind of thing :P. Id much rather trust the collective. So what do you guys think about windows 7? What are some of the pros and cons of it?
