I feel a single generation camera jump is virtually worthless. The D90 was the previous generation of the D7000, the D90 will do almost what the D7000 will do.
I upgraded from a D70s, and I still use the D70s some to this day.
Camera upgrades today can cause you to need other upgrades, computer, offsite storage etc....
I will be happy with the D7000 for a long time, if mine dies, I will replace it, not upgrade, if it is still available.
I gotta reduce the pics to 300K to post them anyway!! LOL
