It's been a while since I actually paid enough attention to actually count them...
This install didn't even have SP1 on it yet ( probably over a 100 in that )... I've also got quite a few of them automated so I just sit and wait for them ( which is what I'm doing now )... after those finish, I do whatever has come out since I made the automated stuff and the others that won't install using that. I think now, after SP1, the count has gone well over 200 or so... but it's a seat of my pants guess now.
