Yes, the new MacBook Pro actually arrived a day ahead of schedule. I was a bit busy this weekend, so I didn't get to spend a whole lot of time on it, but my initial impression is "Damn this is nice!"

Universal Binary applications run really fast. Older PowerPC binaries running under Rosetta don't suck. For the most part they are the same speed that they were on my old Powerbook, and I look forward to the updates that will bring them up to "Zippy" status.

I posted some more specific observations in this thread on the Your Mac Life forums.
