IMHO I think WinxpSP3 is not viable for an average joe anymore. We use it at work but the IT guys know all the tricks to keep it from becoming sluggish. Right now you can't hand a kid an XP computer and expect him to be happy with it after a few months. And you know that no kid wants Dad on their computer fixing thing. But to give XP credit it outlasted Vista. Now I really like Win7, it is a great OS. I am a bit ticked that MS is coming out with Win8 next year. I understand it is mainly to grab the small devices market? I'm buying a new SB system in a few months and frankly won't want to upgrade to Win8 next year or anytime soon. Do we think Win7 will outlast Win 8, the way Xp did ?
