I'll admit I do not run/use such things on my PC and have no need for Win7 whatsoever, I guess I am just old fashioned that way. I do not PC game, thus 4GB of ram = useless, SSD I have no use for as my HDD works just fine, and a touch screen... please, I HATE touch screen crap, especially the iphone.
I find it repulsive the touch screen stuff is becoming more of a standard, and I hope it dies off VERY soon. Don't get me wrong, I am not saying people who use Win7 are idiots, heck my father uses it and he is a brilliant man whom I respect greatly. But I can say as long as XP is supported by most of the software manufacturers, I will not switch to Win7 or anything else until it is absolutely necessary.
Also XP is still the king as far as businesses are concerned, and I'm sure there is good reason for that.
