    A majority of your RAM is "inactive," which is basically free.

    Your RAM usage is pretty normal there. You can tell by looking at your list of running applications in the screenshot. If you add up the "Real Mem," column, it will only add up to about the sum of what's "Active," and, "Wired."

    Edit: The kernel_task represents the OS core. RAM usage here represents loaded drivers, kernel extensions, things like that. Yours again is pretty normal looking. (Mine is at 612MB)

    Double Edit: This is a pretty useful explanation of how RAM is reported. http://support.apple.com/kb/ht1342

    Whoops sorry. I edited my post with the kernel_task stuff at the same time you replied. Basically, it's just the core of the operating system.
