I've dabbled with it now and again (admittedly, about 18 months ago was the last time) and while on a whole it was ok, there were things that "just worked" with windows and Linux stubbornly refused. Like installing my wireless card....
Would be interesting to see how you get on with it on a day to day basis. Im bound to Windoze for work reasons but I think my next laptop will be a mac or dual-boot linux jobbie...
What made you change?
