For tablets windows 8 will be ok. But for desktops it's a load of bullstuff. Linux is meant for people who don't want a stuffty system that fights you with everything.
yeah the system has to be ULTRA stuffty, but if people just wanted to try windows 8 and don't like it, they could easily downgrade to 7 or vista, because believe me, if you want a computer that doesn't support many games or want it to do something on the Internet or run a server, then Linux would probably be best for that.
