    So the touch Pad recognizes when you put one finger on.
    It recognizes two fingers.
    You put a third on and it also recognizes that it is not 2 fingers - does it then take the third finger as one finger or does it actually recognise that it is a third finger?

    Well if you want multi touch on the old macbooks you have to dig for the driver/kext if it doesn't require new hardware. if it does then you *could* get the functionality by buying a new top case (keyboard & trackpad) for your macbook

    Apple has already said that it is not possible to add multi-touch with merely a software update.

    I started a thread discussing this and a competition from CruchGear to deliver this functionality to older MB/MBPs.

    Basically, it's all contingent on how the new MBP is achieving multi-touch as no teardowns have shown presence of a BRCM controller so far. If this is the case, then multi-touch on the MBP is through software emulation which would imply that this functionality could be expanded to older MB/MBPs.

    The trackpads are new hardware.

    Multi-touch capabilities will not happen for machines without the new Trackpad. Period.

    The trackpads aren't new hardware, they are the same trackpads as the previous gen MBP. They possibly have a broadcom bcm5974 on the interconnect board same as the MBA however, this is yet TBC.

    I'm pretty sure that it either doesn't care that you have more than 2 or it just plain reads it as two because there aren't any functions for more than 2 on the old MacBooks

    well one finger moves the mouse, 2 fingers scroll and 3 fingers the cursor stays still, so it does recognise it...

    I would assume then that the 3 fingers are read as a palm (ie. disables the trackpad so your mouse isn't moving when your trying to type). There must be a certain square area that is a threshold for reading a palm or not.

    I saw a post on another forum where someone was using the trackpad (on a Merom/SR MBP) as a MIDI controller under Linux. He confirmed that the trackpad was able to register 3 fingers. I can't find this post now, so take it as you may.
