Says the Nikon D90 user.
You say it like that's a bad thing. I think we can all recommend all we want, but the decision is still up to the poster in the end. D90 is not a bad camera and like he said, is better than D200 in respect to some of the newer features.
As for B/W modes, yes, most cameras have that. I find that shooting in color and then converting them to B/W gives me a little more freedom, though. But that's just me and everyone has their own preference! I can see why you'd want to shoot in B/W and I suppose the camera manufacturers do too, because they put the feature into the cameras.
As far as DSLRs go, especially some of the more advanced ones, I don't think you'll see a lot of those unnecessary scene modes, just the basic ones. Things like video recording and Live View are still new to the DSLR market, it's funny to see a lot of people upgrading from compacts, expecting their Nikon D40 to shoot video...
It seems like this a change you won't mind though!
