Yeah, I have to go with Windows. Its alot more user friednly than Linux (seen it the once) since Windows, you can install it and use it almost straight away. Linux takes quite a long time to get used to.
Plus, programs and games do't run so well or at all in Linux.
its a great little OS for experimenting though.
OS's though should not really be put to comparison since they are all different from each other, and are used for different purposes, etc. Windows is a good all rounder though I think.
