I'm a bit fed up that installing software on Linux is so difficult. I wanted to put avidemux on my computer, but the rpm file I found has so many dependencies that aren't on the SuSE DVD that I gave up in the end. I suppose I could try compiling it from source, but it does seem a pity.
Can't get .avi files to play on my computer either - Google recommends "mplayer" but similar story to above, even with a SuSE 10.1 RPM...
That said, all I did under Windows was web browsing/e-mail/photo editing/sync my Palmpilot/play card games

- Linux copes with all of those admirably...
