In a lot of ways I find Linux actually easier to use and more user Friendly than Windows. I downloaded Kanotix lately and Printer, Soundcard, Cd-Writer worked Immediately. For Scanner support though I had to add a Line in a startup file. I haven't found a Video Format in I couldn't Play with the Videoplayer Xine. I didn't have to install any codecs.
That are just some examples.
Most of the Problems I get with Linux have to do with licensing. Nvidia doesn't want for some reasons that their drivers for 3d-supprt are included in the Linuxdistributions. They provide one one their side though. But installing it is a pain in the a**. I also had problems to play commercial dvds because including the decoder with the Linuxdistribution is illegal in some countrys.
I think I had one single crash in four Month of using Linux (actually just KDE crashed and I had to reboot).
