    Apple usually like to bragg about 64bitness but they only mention it on the iMac specs page and the Mac Pro specs page.

    No mention of it on the MBP page?

    Yes, Core 2 Duo is 64-bit.

    Tiger isnt fully 64-bit however, but that will come in Leopard.

    Napa on the other hand isn't a fully 64bit platform (it can't fully address 4GB or memory for a start, hence the 3GB limit on imac and mbp). Santa Rosa will be.

    Are there any confirmed 64-bit OS installs on the NAPA C2duo platform. I would like to kow if it will support leopard 64 and Vista 64 bit

    And there won't be separate versions (for most components) of Leopard, as they can just pack 64-bit code into universal binaries. A good deal of the nuts and bolts of 10.4 already has 64-bit support as it stands, afaik.

    You don't want to use Vista 64-bit :( Unless it really shapes up in these coming weeks, driver and software support is a massive headache.

    Vista 64bit is a headache for one reason nothing is 64bit so don't blame vista.

    To answer your question No its not 64bit because only the processor supports it and the motherboard doesn't.

    Well, I've been experiencing a hell of a lot of trouble installing the 64-bit drivers, as well as stability issues, on both Vista 64 and XP 64. Perhaps its just my machine, but even with the small amount of 64-bit software I do have, I have yet to have a good experience with any 64-bit MS operating system. Not to mention that the OS should at the very least be able to run 32-bit with little-to-no headache... (Like OS X, Linux, BSD, etc.) Currently, at least for me, it doesn't.

    And back on subject:

    That's not necessarily true. If apple is using the Napa64 chipset, then it could very well have full support. (however, the 3GB memory limit leads me to believe that it doesn't - or at least Napa64 has some other downsides)

    And, finally, regardless of the chipset - it should still be able to run 64-bit applications, just like the Core 2 Duo iMacs, which is the main question of the thread, yeah?
