The Mac mini uses a notebook slot load drive virtually identical to the type found in the Powerbooks. You can upgrade the Mac mini to a Superdrive for only $100 more but it costs $200 to upgrade in the Powerbooks to the exact same specifications. Also if the mac mini really uses a 2.5 inch HD it only costs $50 to bump it from 40GB to 80GB sure it might only be 4200RPM but so are the stock drives in the Powerbook. In the Powerbook one has to pay $125 to go from just 60GB to 80GB but then you get the 5400RPM speed bump but still the cost deferential is much more than the Mac Mini. Even if Apple speedbumps the Powerbooks in coming weeks it will still be G4 and that does'nt Justify the Current Pricing scheme. I think the Powerbook should get a $200 price drop across the board actually Apple should have done that months ago. Even with a $200 price drop on the 12" PB it would still cost more than the 14" ibook. The $300-$400 premium that the PB commands does not Justify the Aluminum enclosure slightly better GPU and a 34Mhz bus boost that makes almost no real world difference.
