It really depend on what you want to do with it... I am going to give you a little different take than the D90, it's what I ended up with.
I got a D200, it's got a sealed metal body, it accepts older AI lenses (Some are really great) and it's got buttons for almost everything you'd want to change. Why buttons, b/c I never have to look at a menu (I keep my eye in the view finder) and can change things on the fly.
It's doesn't have sky mode, or night mode but with a cheat card you can set everything as a beginner.
It's got one older generation process so colours and noise at higher ISO suffers a little but with a 35 1.8, or a 50 1.2 like I got you'll never need ISO 64,000...
The 7000 is very very nice, it's got a feeler for older AI lens and it's better sealed than the D90 just like the D200, D300... but get our your check book.
I can second this. I got a D200 when it was just out (2005, I think) and the D7000 is the first camera that's really tempted me to ditch the 200. There have been some bodies that are better in terms of sensor, processing, etc. But the build, durability, and sealing on the D200 hasn't been matched well enough by any reasonably priced bodies. Also, the older manual focus lenses (as mentioned) work perfectly on it and you can get some stellar glass for very little money.
Really, the three things I'd change about my D200 are high-iso performance, ADR, and battery life. Other than that, it's awesome. Great controls, feel, speed, menus. It feels like a camera built for a photographer, and even with the D7000 I think some of the controls/features feel like they were built for someone who wants nice photos without having to think about what's going on to make them. That is not a knock on those photographers; sometimes I wish I could just turn that part of me off. That part of my wiring exists next to the part that makes me love my old Land Cruiser, my mechanical watch, film cameras, and also that part of me that actively resists getting a smart phone. In some ways, life would be easier if I drove a newer 4Runner, got an iPhone and ditched the SLR, watch, GPS, and MP3 player. But, I enjoy the tools that do what they're designed to do and don't try to be anything else.
I don't abuse my gear, but I do shoot in the rain, on the rocks, and other places where I'm thankful to have an armored metal camera instead of a plastic one. Would I have killed a D80 or a D90 by now? Probably not, but I might have left it in the bag for fear of damaging it instead of getting some great shots.
For me (certainly not everyone falls into this camp) great images and rugged construction beats
slightly better/easier images out of a camera I'm afraid to bring anywhere/everywhere.
