I love my N900 too. As I heared (2009) that there will come a smartphone running with linux OS, I MUST buy it. Before I owned a 5800 and I learned to hate the symbian s60 5th.
I´ve had installed Linux on my (overclocked) Pc a few times, but it don´t support some of my hardware and I mostly use it to play games.
However, I give linux always a chance, because I just like it. And now I always have linux with me.
