    I'm just curious as to Apple's distribution of RAM between different computers and/or different amounts of memory. My results are based on my MBP C2D with 1 GB of RAM. I used the iStat Pro 3.2 widget to determine the RAM allotment after all applications had been closed and the system reached a stable idle. There was nothing running in the menu bar-bluetooth is turned off as well as Airport. Ethernet was connected and I was running about 8 widgets (I dont think this would matter much). My computer has been running for about 5 days as well. Here are my results:

    Wired: 136 MB
    Active: 290 MB
    Inactive: 61 MB
    Free: 534 MB

    I assume most MBP's with 1 GB should have similar results, but it would be interesting to note the differences if any. I'm also interested to see if MB owners experience much of a difference. Lets see what you guys got!

    I don't have a MBP and I don't have 1GB but I'd like to contribute to your thread. :D

    Inactive: 450MB
    Free: 1.09GB
    Active: 266MB

    This was about 5 minutes after the computer had been sitting idle.

    Inactive is basically cache. It's memory that has been used, might be used again but can be thrown away for free space if needed.

    Your total free available ram is free+inactive.
