And just to get that out of the way; SLED 10 is an amazing OS. I can't remeber ever having had so many «how can this be free software ?!?»-experiences. Everything is easy, everything is beautiful.
The concept of open-source, free software is very appealing. Many of the Linux-distros are very good, but I still haven't found one that fits my needs perfectly. Also, my needs will propably change as I become more aquainted to Linux. At this time, my favourite distro is propably Mandriva One, though it would've been Ubuntu if they had had support for restricted formats.
