I think I should get myself a USB mic and switch over to the Mac for my podcasts. Last night's recording got mangled. I originally thought it was the skype out line, and that still might be it. However, this morning I came downstairs and Windows was in a weird state, having rebooted after some (probably unneeded) update. The cursor was showing a flashing CD. I rebooted, and Windows got stuck. I rebooted again, and things seem to be fine.
Looking at the event log, partway through my call last night (and I remember the drive spinning up and the HD going full bore), Windows decided that it needed to read the CD drive. Why, I don't know - the same CD has been there for weeks. It's this kind of incremental bit rot that makes me more and more interested in moving over to the Mac.
