seems like a lot of people held on to their g4 pb until this release. I just didn't like their hardware offerings in the intervening four years (too expensive or too cheap-looking), but I love my new al-macbook. my only annoyances: doesn't seem to work well with a bluetooth keyboard and usb mouse in closed-lid mode. also, seems to always forget the brightness settings for my display and keyboard (adjust brightness based on ambient light is a cool trick to show friends, but when I'm working, I don't want things changing based on whether my head is blocking the light or not).
