I've had the same PB G4 for about 3.5 years and I have used the internal drive about a dozen times. It is a waste of space. If I want movies, music, etc. on my laptop I usually rip it on my desktop and then transfer. Hard drive space is so cheap and CD/DVDs are so slow that I can easily do without it. In fact, once there are updates I might just end up with an MBA, but I'll have to see what the new MBPs bring.
