You haven't tried out any of the Linux releases recently if you believe that.
The 'puter I'm on right now has W98, XP, Mandrake, Fedora, Suse on it, and I often boot up with Knoppix readonly from CD. Mostly using Fedora - my daughter prefers that.
Very seldom use XP any more. Love LINUX --- no problems at all.
I'm glad you've got Linux working beautifully for you, but the thing is not ready for general use. OS X is open source done right. Linux is still playing catchup on the desktop, though it's making good strides.
