Pros: I think Windows 7 does seem somewhat faster, especially after Windows has booted up, but then again, I really don't do much on my PC except for banking really.

Cons: I can blame myself somewhat for this because I bought the professional OEM version, and I planned to upgrade w/ Windows 7 from Vista, nope. I didn't do enough research I guess, but it seems somewhat wrong to me you have to buy Windows 7 ultimate to upgrade from Windows Vista ultimate...so I had to do my PC all over again from scratch.

Overall Review: The other problem I had was a weird one to me, and I have no idea how or why this happened. I have 2 hard drives in my PC, and when installing 7, I told it to install on C...even formatted the drive. After Windows was installed I took the CD out, rebooted the PC, but it wouldn't boot up. The message was can't find bootmgr. I spent a lot of time trying to figure this out, but another weird one was it booted fine as long as the CD was in. I finally started playing w/ bcdedit and got it to boot from C, but how that happened in the first place I have no idea.
