    WOuld someone please compare and contrast for me the rev A vs the rev B dual 2 ghz PM? I heard the A is better than the B. I need some brief comments as to why this would be the case.

    better baseline graphics card, perhaps? top of the range always gets the better card while the mid-point gets the cr@p.

    other than that I don't think there was any difference in the models, price excepted...

    The previous 2.0 Ghz dual differs in the following ways that, IMO, makes it a "better" machine:

    8 (eight) DIMM slots and the ability to address 8GB of RAM versus 4 on current model
    PCI-X slots (100MHz/66MHz) versus 3 PCI slots on current model

    You can sometimes find the "old" machines being cleared out at comparable "new" prices. They're in short supply. (I found one for $1799 on Friday)

    You wouldn't get Tiger or the double-layer drive, though. If anyone has any better information, please leap in. :)

    I'm not up on all the technical aspects. It has been often mentioned by members on this forum that It's not a good idea to purchase Rev. A of a Mac. So being that the new on is a Rev. B, means that problems have been corrected in this model. There is also the dual layer 16 x super drive.

    I certainly don't agree with that assertion, owning a Rev A myself. :)

    In fact, after having a Rev non-A eMac (died) and non-A iMac (DOA) I think it's a crap shoot either way.

    My Rev A is the best Mac of them all. Rock solid and no complaints. :)

    Rev B based on video card and CompUSA needing to clear out last month's "old" inventory. A Rev A would be pretty difficult to find these days. Rev C are shipping from Apple right now.
