    I'm just wondering but i have a 160gb hd and seeing that i have 60gb free, my user folder containing 58gb and application folder having 6.7gb... that leaves me 130gb all accounted for other than the OS. Is OSX really 20gb in size?

    If you actually ask for info on the drive it'll show the capacity as 149GB or so.

    This is due to HD manufacturers using 1000megabytes/gigabyte when calculating GB as opposed to the "correct" 1024megabytes/gigabyte. Here, (160GB/1024)*1000 give you a value of 156GB. There is also a slight loss due to formatting space (usually about 5% or so, at least in NTFS systems, not positive with HFS+).

    Side note: "memory" usually refers to system memory. "storage" refers to hard drive space, which you are talking about. Some people make the mistake because they're both measured in the same units of measurement-- bits, bytes, megabytes, gigabytes, etc.
