Ive used my Apple 17" PowerBook every day since they first came out (we have a Rev A machine). It's about 6 years old at this point. I'm not a war correspondent or anything but it gets used in a variety of locations in the house and its made several cross-country trips. It was in use as a back-seat DVD entertainment system during a rear-ender that totalled the car we were driving in, and never missed a beat.
It's suffered a hard drive failure (I replaced it myself) and it's had one replacement battery. The latch is a little weak and sometimes only one side engages. Other than that it works flawlessly.
