However - I doubt whether the data loss is really visible or relevant for any users, except in extreme cases of (for example) astrophotography. The biggest advantages of "shooting raw" are present in both schemes. I can confirm that the D7000 also offers a choice between lossy and lossless compression.

The D70 is a rather old camera by now, and I believe Nikon now offers a choice between uncompressed, lossless compressed and lossy compressed NEFs on its models, at least that was the case on the D3, not sure if it is on the prosumer and consumer-level cameras like the D3100 and D7000.
