It is so much better than windows (except for the fact that it can't run any windows software). Still, I'm a Windows fan.
I'm quadruple booting Windows XP, Vista (with IIS and VMware Server- i must be insane), SUSE, and Kubuntu (ewwww...) and Knoppix 3.8.2, 3.9, 4.0.2, and 5.0.1 (I have cds of all of them)
And in VMware, I have installed/used Freespire/Linspire, Debian, Fedora Core 2, 3, 4, and 5, Ubuntu (*cough**awful**cough*), PCLinuxOS, Mandrake, Xandros 2.5 and 3, Puppy Linux, FreeBSD, and a few more I can't remember... it's kinda sad...
I never delete any ISOs, either... I should be a mirror...
