I've had super good luck with apple, recently. I had my logic board on my iBook/700 fail, and got a new one for free (I know there is the repair ext. program) even though I had painted my iBook blue (ie, voided any warranty) now, I just got a superdrive PB w/ 5400rpm 80 gig HD for 1379 (yeah student developer's discount!)
It looks like I should have ordered online from Apple, instead of having bought my new 1.33GHz 12" PB from the local Apple store.
Anyhow I'm happy. I upgraded from an 867MHz 12" PB, and it only cost me about $250 (as I sold the other one). The only spec in which I downgraded was RAM... the old one had 640, and the new one has 512. The RAM came free. It came from the 1.25GHz 15" PB of a friend. He upgraded to 2x512 modules and gave me his old 2x256 sticks.
and all the superdrives that apple have produced for at least the last 18 months are dvd-rw, apple just say they're dvd-r because they don't officially support the -rw in the OS. programmes like toast can do the rewriting thing...
