I'm probably the only one around here that went from Mac to Linux... I decided to do this after a number of frustrating problems with hardware: ethernet port not working [1] and a severely swollen battery (although I followed all the advices to prevent this) which was not covered by the warranty "because of the laptop's serial number".

I decided to buy a Lenovo E540 a couple of years ago, on which I run Linux Mint: I like KDE's awesome interface add much add I liked Mac OS X's. I wouldn't ever go back...
