I've come to like my iBook G4 more since I've been running Debian on it. The advantage, which no fanboy can dispute is this, free upgrades. I got sick of this or that not working under 10.3 (no Java updates, for example) and so I thought "I'm just not shelling out $100+ for a new OS."

I do appreciate that OSX is now an official UNIX, more power to 'em.
