I stopped by a local Apple Store after work and found one in stock.
So far, it's not that exciting since it feels almost exactly the same as my Macbook Pro. The keyboard backlighting is actually more legible with the backlight on black instead of on silver. The single mono speaker is much louder than our white Macbook, but not as loud as the stereo speakers on the Macbook Pro. It's also a bit strange to have the sound come from only one side and behind the keyboard.
I found the file transfer to be fast enough over wifi. I had about 40 gigs of data transfered in a couple hours. The network utility said it was connected at 130 Mbit/s.
We'll see what happens when I use it for a couple weeks. It might replace my Mom's iBook G4 if I find that I can't live with it.
