I tried Windows 8 on a laptop at a store an I hate it. The start screen sucks. Whenever I tried scrolling the screen left or right, I accidentally moved some metro icons. I really wish they would at least make the start screen a choice, so they don't piss off people that really liked the start menu. Metro would work well on a tablet PC or maybe even a laptop, but not a desktop computer. Controlling the start screen would suck with a mouse. At least with a laptop's touch pad, you can swipe it with 2 fingers to scroll left and right. Paying to be able to play DVDs is bullshit. Windows 8 sucks. I'm sticking with Windows 7.
I'm sure I will never get Windows 8 unless they fix it's problems.
