Should i get the free vista upgrade?

If you want to try it make another partition. One could have XP and one could have Vista. That's what my friend did. I tried Vista on his computer. It is good. I think you should give it a chance. If your computer is compatible with Vista I don't think there is anything wrong with it. Except software compatibility. But if you have vista and xp on your computer you should have nothing to worry about. I hope this helps you! If you want to make another partition. I can find a link to show you how. Just message me.
