As I wanted to leave the house, a courier van turned up with the D80+lens (battery grip is delayed). Will play a little at lunchtime but so far it feels really nice. Not much differnet to the D70 but the big viewfinder and LCD make a difference already. The Sigma 18-50mm f2.8 feels nice and fast, too.
Good thing I ordered loads of SD memory, 169 RAW photos on 2GB isn't very much...
