I disagree.
My laptop is non-touch screen, and I am running Windows 8 without any problems. It's great to run and is so easy to run as well - easier than Windows XP/Vista/7. Sure, it is probably designed for Tablets or Touch Screen Computers, but it definitely works a treat and is brilliant on normal laptops as well.
How do I know? I am running Windows Eight Professional.
My mom has it on her laptop without a touch screen and i'm fine with it
Yep, I have Windows 8 on my PC, no problems at all with it, and it certainly isnt hard to use.
