Tiger arrived today. I've had a chance to compile and suppress warnings in Senuti and will check out my other applications over the next few days. So far I am extremely impressed with Tiger. It continues to amaze me that every major upgrade of OS X is significantly faster. I haven't managed to check out all of the 200+ new features yet, but the ones that I have seen appear to be all that Apple said they were. I'd recommend going out and getting a copy as soon as you can, especially those of you still on Jaguar. It'll be worth it!
