Pretty simple. Windows 8 blows! Although the youngsters may like and use the tile-ey thingies on the tablets and phones, as a desk/laptop OS it is horrible. It is not just different the way 95 was from NT, or 7 from 2000, it is bloated and weighted toward all the social tile-ey thingies.
No recognizeable start menu (added later), no means to go directly to system functions, or paths to system functions in a familiar way.
All in all, sticking with 7 until the wheels fall off, then moving to the ultimate windows patch, Linux.

I'm well along the way with Linux. I've got a couple of machines with 7, the rest with XP and not moving beyond them. Using Mint and LMDE, depending on computer.
