I was at the keynote this morning. Afterwards, I went onto the floor and checked out the Macbook Pro... Build quality and fit & finish is nice - on par with usual Apple specs. The keyboard and trackpad feel nice (I use a 17" now). I asked the Apple rep what the battery life was, he said "we're still determining that..."
I said, lets find out now, and I pulled the magnetic charger cord, the 1.83GHZ machine said 8:10 remaining... Now, Airport and bluetooth were off, but screen brightness was on max and load was not heavy so you can take it for you will. I did, and ordered one... My battery life test is far from conclusive, but I was happy to see double the number I normally see on my 17" when I first pull the plug in a similar state.
iSight has a cool green light at the top of the screen bezel near the lens that is on when the camera is active.
