No one should fear buying a Windows 8 computer which has the main problem of no start button plus when you boot up you don't see the traditional Windows desktop
All you have to do is download and install a free program that will give you back the desktop and start button. Been there and done this.
Here is one of those programs that make 8 look more like 7 http://download.cnet.com/Start-Menu-8/3000-2072_4-75852660.html There are others
I d/l a program so I would have the start button and the W7 feel. I sometimes hit the windows key and have to deal with it and keep getting it by accident. So, I restart and all is well. lol
