Mac OS X Leopard has arrived

Actually, the small box arrived about an hour ago. Clearing some old work source repositories from my hard drive and other general 'housekeeping' duties. I haven't eagerly anticipated a new OS release for a long time: I would probably compare this to the time when OS/2 2.1 was released with its full 32bit Presentation Manager or perhaps even OS/2 Warp 3 with its UI enhancements... As to what features I am looking forward to exploiting, I would say in no particular order: Spaces, XCode, DTrace, Shark. There is a bunch of other 'nice to have' features... I guess I will see how well I like it after I install it.
