I received my MBP yesterday and have had some time to play with it now. I thought I would give my general impressions.
Everyone keeps saying it, but it hits you with usage and bares repeating: it's bloody quick. I use a first generation G5 tower (Dual 2.0 with 2 Gigs RAM) as my primary machine and I was shocked to note that the new MBP (2.167 with 2 Gigs RAM and 7200 RPM HD) is noticably faster at most things.
I just spent all morning running the battery down for calibration, building open source software and the like. I do this kind of this all the time and have a solid feel for how long it takes. I was repeatedly surpised by how fast it could finish. This was all on battery power. (A second CPU doesn't do much for compiling.)
I'm sure I could find a test where the desktop would win. I suspect burning a DVD would do it, pushing all that data over the faster bus. However, the MBP is a real contender. Believe it.
Moving on to other features, the battery life seemed good to me. It gave two hours and fifty minutes of usage this morning when I was trying to run it down. I was doing installs and compiles the entire time, so it didn't get much rest in there.
I really haven't had any problems with the machine. So far, I haven't detected a "whine" of any kind. The screen angle and MagSafe don't bug me, but I always use a computer at a desk. It get's warm when working hard, but not hot. Nothing uncomfortable. It does fit fine in the bag I bought with the machine, a "Marware Sportfolio - Black Ice Case".
Finally, I would just like to say that the little features really add up. The backlit keyboard, MagSafe, scrolling trackpad, remote (Keynote gets a huge win here), and built-in iSight really push the machine up the scale. It's pretty darn high in sex appeal.
So far, I couldn't be happier.
