Yes, I have the D70 (which is very close to the D70s). I like it a lot. I have always been a Nikon fan (2 SLRs, 5 point and shoot models, 1 DSLR), though my Nikon glass isn't getting used on the D70 as the kit lens is very good IMO.

It is a lot like the Apple/IBM debate, discussing Canon vs Nikon.

As others have commented, both Canon and Nikon are making some very good cameras. Hold each and try them out, they do tend to feel different. Pick the one you like the feel of if you don't have any great lens collection to sway the decision one way or the other.
