I like the freedom that Linux gives you. Right now, I have a Compaq with XPHome installed. I would like to upgrade the motherboard to an AMD64, but I cannot because the reinstall discs will not work with a motherboard that has a non-Compac bios. So I am tied to this hardware as long as I want to keep this copy of XP.
If I was using linux, there would be no problem. I have second (older)comp that I have SUSE on, and I am learning to operate it.
I like the fact that it is free, secure, and has no hassles of product activation. As far as use goes, it is just different, not that it is better, just different. If you want to give it a try, look at
SUSE LINUX Live-Eval , it can be used just from the DVD, no install required.
