Okay, I went for the gusto and have completely erased my PowerBook in favor of a virgin installation of OSX.

Absolutely no regrets. My PowerBook was having serious problems, which I thought were all hardware related... but every one of them has gone away since the upgrade.

Radio and Frontier both run better under OSX. I've had zero stability problems, and I have the port forwarding issues all worked out for Frontier (haven't bothered with Radio yet).

My mail client runs better under OSX.

I can't believe what I've been missing.

I didn't watch the game, but I just heard that the Patriots won.

That's too weird. Next thing you know, the Curse of the Bambino will be lifted so that the Red Sox can win a pennant, and the Celtics will actually show some post-Bird greatness.

(I'd mention the Bruins, but hockey is boring.)
