I would have to agree with the people on this post, that windows 7 does come across as XP SP 5.. it is far better than vista.. but on the whole.. still just "feels" slow!.
It is quicker than vista though.. so that is a upgrade
.
But on the whole it does appear that MS did listen to the complaints about vista and re-done it for windows 7.. but on the whole. I would still use Linux for my normal desktop and any games that will not work in linux will need to use windows for.
