If this still isn't enough to satisfy your mac hunger, get a program called bootskin.
and if you still
need more, just go to www.deviantart.com and search for skins for any of your programs or for gui.
STILL not satisfied?!? if you have to, check out this
instructable. that is how you simply install mac os x onto your pc using osx86.
ok, if that's enough. just get a freaken mac.
oh, and for fun, if you have a nokia phone, you could install these themes i uploaded.
