Pros: There is so much good about Windows 7. It installs easily, it runs stable with none of the problems that were in Vista. Considering how complicated the app environment has become, this OS is a really amazing thing.
Cons: Windows Update needs an overhaul. There are too many updates and too many that require a reboot. When you buy this version with SP1, you still have to download a boatload of patches and updates to get up to date. MS need to figure out a better way to update their OS.
Summary: I installed this for a customer on an older Lenovo ThinkPad and it worked spledidly. Windows 7 is the best version of Windows available. It can be used to replace Windows 8 when you realize that you don't want it.
Pros: It's not Vista, It's not Windows 8, Not bloated
Cons: Better than other Windows OS's, but it is still Windows
Summary: Went to this from XP and jumped over Vista. Works good, less bulky then vista. No real complaints. Good option if you want to play all games out there while linux catches up. Might switch when it does.
