Windows 8 doesn't impress me, regardless on how they make it look, or how they advertise.
Call me weird, but once something impresses me, it's hard to switch back.
Linux impressed me. It was a distro back in 2005 I think. It was neat to use a distro for more than a week and not have that 'bogged" down feel that Windows gave me.
I had a clean harddrive, complete partition, and even after a few days, Windows started to bog down. I only had Call of Duty 2 running.
Tried the iMac, heard from others how good it was. Blah. Just blah.
I'm with Linux, no matter what Windows can do. I am not impressed with Windows or iMacs.
That's just the kind of guy I am.
