I had to get a new Macintosh Powerbook (more on why later). I have 17", one that's a rev back from current. Because of the amount of travel I do, I decided to go with the 15". Same reso as the old 17", and 1.5lb lighter. You can also get them from the Apple store (no waiting) with the 7200 RPM drive in it. Woo hoo.
So far, the coolest thing was the setup. Turn the machine on. See it say "welcome" in 45 different languages. Take the old 17", bring it up in Target Disk mode (it doesn't boot the OS - it just turns into a firewire drive). Plug it in, and wait 5 hours. When done, the 15" is *exactly* the same config w/ user data as the old 17". Very, very cool. I'm up and running with no environment change.
