minecraft runs on windows 8, and ever game i have tried runs just fine on windows 8.
I have yet to find any software or games that wont work with windows 8 (even ones that were made for windows 2000 or windows xp run w/o problems). And i never even had to run them in compatibility mode. (which you should know how to do that, its been there since vista, if the problem ever came up)
As for the interface, its not hard to get used to, in less then an hour i figured out everything and liked it. (im not sure where the win8 hate comes from really lol)
I think people hate windows 8, because its un-piratable :P
Btw when setting up windows, id recommend you use "custom settings" rather then "express settings". (someone i know did express, but it may have been something else, but it was a mess. i did it for them, and works flawlessly lol)
EDIT: i have experience with windows 8 (not the preview which everyone seems to base things on...)
It uses LESS cpu, LESS ram then windows 7, and run quite a bit faster....
And he isnt asking about upgrading to windows 8, are you people illiterate?
Hes wanting to buy a new laptop, and all the new laptops come with 8, hes asking if he should go for that, or find an older laptop with 7 (or buy win7 to replace the 8).
And no, windows 8 that is pre-installed should be left on, as 8 is better then 7 (in most all ways that ive seen).
It may be bad if you are retarded, and cant look up things like http://lmgtfy.com/?q=windows+8+tutorials
(my 46yr old aunt who hardly uses computers, and when she did it was like xp/7, figured it out w/o me helping at all... but shes intelligent and know how to use resources....)
So if you cant figure out win8, you may be retarded...
and the fact that 98% of windows 8 is IDENTICAL to windows 7.... the ONLY change is start menu is replaced by metro (which is better anyway, especially for laptops)
