Nikon D40 or D60

I am contemplating getting a DSLR soon. I have a Pentax ZX-7 Film cam that collects dust and I want to get a new Digital SLR to go along with my Sony point/shoot...
Anyone have any feedback on D40 and D60? I have no aspirations of using the camera for much more than fun/recreation so I am not looking for terribly high resolution. Any feedback will be appreciated. Any features that are must have?

Thanks.
