Maybe you had more due to having the SSD.
Also were you at 10.6.3
Yeh I was 10.6.3 before.
I did have some other smaller updates to install, but havent bothered TBH (update to iMovie, remote desktop, and iLife (which I dont use except for iMovie), since everythings running fine and I dont really need the updates.
Or do you just tend to install all updates, whether you need them or not??
For example, the iMovie updates adds improved stability when importing from Aperture - something which I never do anyway!
