same here
I updated both my wife's and my Powerbooks G4, her's 15" Ti 1Ghz Superdrive, and mine 12" Al 1.33Ghz Combo via software update and I noticed that in her SU that it's 16.6 MB or something like that, while on mine it's the normal 28.8 via SU. Anyways, I updated both as said, her's with the 16.6MB update and mine with the normal, just to see what'll happen. I know I'm taking a risk, but why not? After all, all data are backed up. Anyways, no problems on hers or mine, only I got a few pop-ups on Safari since then, but not on hers. Hmmmm...... wonder what's up with the new update?
