    Just picked up the 64gig Air.
    Under General Settings it lists the device capacity as 56.7....?
    I realize the iOS must take some space, but over 7gigs!?!

    It's not just iOS, but the apps installed. Also, you didn't start with 64 GB, because the formatted size is smaller than that.

    I forgot what the thing is with memory but it always goes down as you increase the size. So 128 will probably be 118.

    sure the apps take some space I installed a few and my available capacity is showing as 54.6GB. In other words it reads:

    Capacity...56.7GB
    Available..54.6GB

    It's the Capacity of the device shown as 56.7 I find strange.

    I expected that to show as 64GB

    As I said, the formatted capacity is less than the hardware capacity, as is true for any storage device.

    Read the fine print on virtually every electronic device that has memory. Manufacturers list memory as 1 GB = 1,000,000,000 bytes (decimal 1GB), but the actual memory is reported in chunks of 1GB = 1,073,741,824 bytes (1024 * 1024 * 1024, or a binary 1GB). So 64 GB (advertised) = a reported value of 59.6 GB.

    A Google search of "decimal binary hard drive" will turn up lots of links and examples, going back many years... That's just the way it's done.
