maxebb,
I'm sure documenting your experience with the apps would just be asking too much, so let me relate my experinece with Adbe products on OS X.
PhotoShop (6.01) - It opens fast and actually runs faster. I have had no problems running it in Classic, up to and including using large Action scripts and batch processing 20 to 30 files.
Illustartor (9.0.2) - Once again no problems to date, and the speed under Classic does appear faster (I haven't benchmarked this with anything like I have in PhotoShop).
GoLive (5.0) - The only Adobe product I've had problems running in Classic. And, actually the only problem I've had is the one Adobe documented, when using the click and shoot functions the arrow does not render in the OS X screen space. To avoid any complications I just boot into 9.1 when I want to work in GoLive.
Acrobat (4.05a) - Has given me no problems, but I have noticed a slight lag in creating the actual PDFs. Not sure where that comes from, but it is not unusable.
ATM (4.6.1) - It has worked just as it should in 9.1. I haven't determined whether it really matters in OS X, but then again there isn't a whole hell of a lot detailing how OS X handles Fonts, besides to say it recognizes quite a fe different ones and you can make them active by just sticking them in the Fonts folder and relogging.
I'd be curious to know how things like After Effects and Premiere have worked in Classic. But, there's my experience, at least.
Ciao
