Well, a couple of notable bloggers at least. You'll find that there has probably been as much, if not more, trade in the opposite direction. (I know a couple of people who have quietly gone back from Linux to Windows but keep quiet about it!). You're right though - Linux, particularly Ubuntu - is the 'cool' alternative. So it really depends on your motivation. Some people have always dug the hippy side of Apple, but some of us like the quality and design side. >Plus Linux does everything a Mac or PC can but for free. In the most raw technical sense that is true - you can edit videos, burn DVDs, rip audio - but Linux is still years away from producing something like iLife or iWork with it's themes. Also most Linux developers have come from a Windows or X-Windows background - which means their app design skills often lag a little behind what Mac users are used to. It will be interesting to see if Doctorow sticks with Linux. (The weird thing was discovering that someone so high up in the EFF wasn't a Linux user already).
