As soon as I came back to France I went to the electronic shop and bought a Mac Book Pro.
I have a Mac Air 11" since over a year, I use it as a bedtime video player and morning web browser :-)
But otherwise, since 1993 I only have had Windows PC, before that it was Atari and Amiga but that's so long ago now..
Anyway I've decided that in 2013 I'll try to switch to Apple almost exclusively for the computer usage. Now I've invested quite a lot in this Mac Book Pro (15.4" retina display, 512GB SSD, Intel I7, 2.6Ghz, 1GB graphic card, etc.)
