    A very neat widget !

    This little utility lists under "Memory"
    Wired
    Active
    Inactive
    Free

    The last two categories are self-explanatory; but I don't understand the "Wired" category. Also, why is "Inactive" not part of "Free"? Is "Inactive" reserved for some application?

    Appreciate your comments.

    You can basically consider all free + inactive memory as free, in essence. The most useful tool to look at is the indicator of pageouts -- this means information is moving from real memory to VM. If the pageouts are rapidly increasing, your computer could do what you're doing more quickly and easily with more memory (either by quitting applications or by buying more RAM).
