    iStat is reporting I have a swap of 20mb/64mb and ever growing Page In's and a few page outs.

    I always show at least SOME free memory, usually >1gig and inactive between 200 and 700 - why am I having a swap file at all?

    I'm not sure if I've hosed something. Is this normal?

    No need to worry, that's just the nature of OS X (and Unix in general). If I'm not mistaken, OS X has multiple swap files in use at once so it's just a normal thing for there to be swap.
    I wouldn't worry about it unless you are experiencing really crappy performance.
