    The kernel is the Core of the OS, and allows the software to interact with the hardware. All UNIX/Linux systems are built on solid kernels, and the Mach Micro-kernel is what OS X uses.

    Can you give us screenshots of System Memory and CPU under Activity Monitor?

    Generally, kernel_task skyrockets with certain tasks. DVD Imager on my G5 shoots not just itself up, but several system programs when processing.

    I'm slightly skeptical about "losing" half of your RAM. Does it actualy go to "inactive"?

    I noticed a lot of pageouts - how long was the system on before you took the screenshot? A lot of programs keep their information stored in memory, regardless if it was recently shut down.

    I think you are fine.
