I noticed this too, and I'm now convinced it may be the reason I could not duplicate keeper rates with the D7000 as compared to a D300 and D2Hs. Subjects were running dogs.
I'm sure I'd get used to it over time but going back and forth between bodies would be an issue for me as much of my dog action work is in the dead of winter and I'm wearing gloves. The D7000 shutter and gloved hands are not a great combination, in my opinion. This may well not be of consequence to most shooters.
I've decided to pass on the D7000 and keep the D300 around for a while longer.
