I use W8, i love it. Just more fun to use
My laptop runs on direct current, meaning i removed the battery. It stays on 24/7 except for some updates here and there.
Installed W8 on a friends pc, he uses it for transferring stuff to memory cards(he has a shop) and his specs are unbelievable;
AMD 64, 1 gb ram i think 128mb or 256mb video card, and W8 works flawless on that!!!!
And yes, W8 was specifically designed for touch-screens.
