what os?

i have
Win 98SE
Win ME
Win 2000 Prof.
Win 2000 Server
Win NT 4
Win NT 4 Server
Mandrake 6.1
Red hat 7.1

So far I like them all except recently i want to kill the ME machine

mac always the under dog but with the release of osx with a unix kernal i think it has the chance to go far
although the lack of security pages for macs i still belive it is the most stable and user friendely os after of course *nix machines
