Jaguar, now I'd have to think about that.

I've honestly never even seen Jaguar, I switched 8-o , from MS windows when Panther had just been released.

Tiger is good, the install size is minimal and there is still a lot of apps for 10.4 and above, not as many for 10.3 and very few mentions of 10.2 anymore.

When I first got my MDD I had aspirations of keeping it in a virgin state, but since I've already violated that when I upgraded the Fans I do not feel guilty running Tiger.
