I have to question the long-range wisdom of buying a body that requires AF-S or AF-I lenses for autofocus, but of course if you're only planning to stay within a certain range of lenses then it's not a problem

And of course, one can always change bodies later.
any particular reason you skipped on the d40x?
According to DPreview, the differences between the D60 and D40x:
EXPEED processing
Image sensor cleaning system with Airflow control system
Automatically rotating user interface (for using camera vertically orientated)
Stop motion movie function
New stabilized kit lens (AF-S DX NIKKOR 18-55mm f/3.5-5.6G VR)
Eye sensor
Electronic 'rangefinder' for manual focus
Active D-Lighting with dedicated button
In-camera Raw processing
New JPEG retouch effects (Cross Star and Color Intensifier)
so maybe more attractive features?
