Here is an interesting beginning of a guide coming up about Nikon D90

“Nikon D90. At 12 MP, and with the list of cool features I outline below, the D90 serves three purposes in the Nikon line.  It’s easy enough to use to serve as a first dSLR, and won’t overwhelm anyone who wants to move slowly into more advanced features.  And yet, those features are in there, ready for you when you’re ready for them.  It also makes a great upgrade from the D80, and works as a backup camera for those with a D300 or other more advanced Nikon body.  Other than the flexibility you get with the D300’s four Shooting banks/four Custom Setting banks, you don’t lose much by going with the D90.  I’ll know more when I can compare sensors and high ISO image quality between the D300 and D90. I expect to see the D90 sell for about $999 with the 18-55mm VR lens, which makes it only about $50 more than the current price of the D80 with that lens.  If you read on, you’ll see just what you get for that extra fifty bucks. ”
