ummm yeah it does, you can just install the xmms or any other media player out there for linuxmegapenguinx said:You should note that Ubuntu does not support mp3's.
this should help: https://help.ubuntu.com/8.10/windows/C/index.html
as for ubuntu i've never really tried it, i've been running either slackware or gentoo on one computer for about 10 years now. i can't say enough about how good it is. when they upgrade kernels there is a lot of times it SPEEDS the os up, unlike windows that has only had 1 os that has done it and it's not even out.
as for security, it's no brainer really, the only other consumer os that is more secure is openbsd. and the stability is great, there are times when certain aps aren't that stable, kde 4.0 i'm looking at you tho 4.2 is supposed to be great, even when apps such as x-windows crashes it won't crash your os, just the app.
as for window managers, i'll have to say try out kde or E, they are great window managers and have some pretty darn cool eye candy. tho gnome isn't that bad, i found it a bit clunky compared to the others. you don't need to keep the same window manager that it's installed with, i'd say change it
