I would prefer a DSLR without video mode. I wish that was an option. I don't shoot video at all and have no plans to start. I do use A, S, and M modes only. I never use P modes or any of the presets.
However, I am not sure my needs call for a full frame camera just yet. I love the performance they offer as to quality, particularly in low light, and the fantastic use of high ISO numbers, but I really do not use a camera in low light very often. I sure do not need the FPS they offer.
The biggest thing about FX is the initial cost of the body. For now at least, way out of my budget. But, any camera is out of my budget at the moment.
I am simply thinking way ahead in terms of next camera.
Mike, I mentioned making the jump from a D90 to a D600 only because I wanted you to know there wasn't a big learning curve there and wouldn't anticipate a big learning curve if you upgrade from your D90 to a D7100/D7000. Sorry if you misunderstood my post! The switch can't be all that much different though.
Oh...one thing that DOES bug me is when I use the +/- button on the top of the D90. To underexpose, the subcommand wheel needs to go to the right, and to raise exposure it needs to go to the left. It is just the opposite on my D610/D600. Not sure how it works on the D7100/D7000 but it's a pain when I switch back and forth between cameras. Other than that, the switch was pretty seamless going from DX to FX so I don't anticipate it would be difficult at all for you to upgrade to a more current DX body.
