CS2 vs CS3

I've looked over the specs for both, and I was wondering if it truly is worth the cost to upgrade? What do you use most in CS3 that you didn't have in CS2?

One biggy, is Camera Raw, you now can use it on your jpegs.

Too much to list, it's worth the upgrade.

"Supposedly" ACR has undergone many upgrades in CS3 that is supposed to be overall better for color management and everything.  Again, not a guru, so take it for what it's worth.  However, I know of very few photographers locally that have CS2 that have been convinced to upgrade, so there's that...

What about Bridge in CS2 compared to CS3?  I've read that it's supposed to be faster, but that was part of Adobe's marketing and it would be better hearing from someone that uses it instead of an advertising person. 

I may also take the upgrade as a chance to get Lightroom and it seems like that and Bridge overlap functionality a lot.  Do any of y'all use both Bridge and Lightroom, or is Bridge sort of a Lightroom lite?

I could never get Bridge to work for me in the first place. Two minutes into using it, it always locks up on me.

Doing some research, I find that A LOT of users have problems with Bridge locking up their system.

Yes there is an overlap, gives you the ability to do what you want in the program you want. I love lightroom but once I've exported the images I delete the database. Makes it run tons faster and I do everything else in photoshop/bridge.

Seems bridge CS2 locked up pcs, CS3 runs slow on 2gig ram but fine
