My father has a touch screen TV, it's the stupidest idea ever, grubby hand prints everywhere, what a waste of money.
Windows 8 is a joke, I played around with the beta of it for awhile and it is easily just as bad as vista if not worse, horrible support for most devices, crap looking interface and unstable to boot. If anyone is thinking of going out and buying it my advice is don't, stick with XP or 7, at least until more developers start writing decent software for them and making sure there is no driver issues.
