    You're suppose to have 59.8GB for a 64GB SSD. You're missing 4GB technically.

    If a 64GB SSD Costs 1000 more(1000/64= 15.5) Apple is ripping ssd buyers 80 bucks for that missing 4GB.
    I'm glad I went with the hdd model.
    SSD will be significantly cheaper early next year, if the industry keeps advancing this fast anyway.

    Still no answer from Apple or explanation from anyone...

    This is the latest in a number of threads on this topic but if you read them you will not find out why there is 4G missing from the SSD. If you buy the SSD form another sources and format it you have full capacity. Why not on the MBA from Apple. It just find it frustrating that Apple does not provide an answer.

    Im assuming the "missing" 4GB is made up of pre-loaded programs on the MBA maybe.

    OK - so maybe not everyone has read the other posts. No MBA users get 59G on the SSD. But if you buy the same SSD drive third party you get 59G. it is not software or swap space or anything like that. You can totally reformat the disk and cannot recover the 4G. It is a mystery. I love Apple products but when you spend this much on state of the art hardware you should be entitled to honest marketing and top level customer support.

    I moved to Apple because I hated the arrogance of MS. (knowingly) Putting out crap and letting the customer work it out. Apple is different but as they become more successful I fear they will feel less vulnerable to customer perceptions.

    But the model number says: MCCOE64GEMPP with 64 in the code?

    I find this image to be appropriate in this case. This is the way HDD manufacturers do their thing. You would get laughed out of the room.

    Check your 80GB, its not got 80GB. None of the iPods get the full specced GB when connected. Its how HDs are marketed by their manufacturers, its not an Apple thing.

    apple is not scamming anyone guys:

    Decimal vs. Binary:
    For simplicity and consistency, hard drive manufacturers define a megabyte as 1,000,000 bytes and a gigabyte as 1,000,000,000 bytes. This is a decimal (base 10) measurement and is the industry standard. However, certain system BIOSs, FDISK and Windows define a megabyte as 1,048,576 bytes and a gigabyte as 1,073,741,824 bytes. Mac systems also use these values. These are binary (base 2) measurements.

    To Determine Decimal Capacity:
    A decimal capacity is determined by dividing the total number of bytes, by the number of bytes per gigabyte (1,000,000,000 using base 10).

    To Determine Binary Capacity:
    A binary capacity is determined by dividing the total number of bytes, by the number of bytes per gigabyte (1,073,741,824 using base 2).
    This is why different utilities will report different capacities for the same drive. The number of bytes is the same, but a different number of bytes is used to make a megabyte and a gigabyte. This is similar to the difference between 0 degrees Celsius and 32 degrees Fahrenheit. It is the same temperature, but will be reported differently depending on the scale you are using.

    The SSD in the Air has 55.9 GB. That's awfully close to that 60 GB number you posted, right... not 64 like the Air should have.

    The exact conversion from the advertised capacity of hard drives (base 10 based) to the amount of space the computer sees (base 2 based) is (1000/1024)^3 or .9313.

    Based on that the 64 Gb SSD in the Air should have 59.604 Gb available. It doesn't and it's not clear where the missing 4 Gb went. I'm really surprised apple hasn't addressed this yet.

    The manufacturers truncate when they list the hard drive space; take a 320GB drive.
    320GB drive is 320,072,933,376 Bytes of space in decimal; in binary is translates to 298.1GB

    I think Anoz gave the answer for this, 55,5 is close to a 60GB drive, if they advertised the drive as a 60GIG SSD it wouldn't be a problem,
