    Just a quick question regarding the stand by battery life of the MBP, obviously it's not a patch on the Air's, but what can I expect?
    Also, could Apple bring the 30 day battery life to the Pro with Lion, or is it a hardware configuration as opposed to software?

    Thanks

    Unfortunately, there probably is some hardware limitation here, but on the surface it would seem like it could be done with software.

    The reason why I think it could be done is it seems that all the MBA is doing is just entering the "safe sleep" after 1 hour of standby. Now, all MacBooks today can currently "safe sleep": Close your macbook, let it sleep and either let the battery drain till empty or take out the battery, when you turn it on it will restore from safe sleep, meaning that the RAM contents prior to sleeping will be loaded back from the hard drive.

    It would be nice for this to happen to older MBPs, but it likely depends on a software controlled hardware switch that kills power to IO and other hardware.
