I have been deciding to run Linux for quite a while, since Windows 2000 and even back in Windows 95 days. I just was waiting for certain programs to be available that I can't seem to find for any platform but Windows or my Macintosh and of course those (4 in total) programs keeps the need for Windows. I just came back to XP from Macintosh last month and twice I have had a worm or a virus take out my system... the spyware problem and that combined have motivated me to switch, but the clencher was the DCRM horror stories in the new Vista. Time to be Open Source all the way for this kid. Of course, if Amiga 4 would get fully implemented and run on the PC hardware, I would love that :-) AMI was the way I wanted to go in the first place.
Anyhow, SuSE is quite nice to me.
