The 70s handled the situation. It is my main camera now with a D70 as its backup. I am beginning to think that that series is a gem like the old Nikkormats. (I have 2 of them from a former life.)
Since I never change cards, I do not care about mixing them. When I go to the D80, I will get a good 4 or 8g card and just leave it in. Changing cards seems dangerous. The CF cards have delicate pins connecting them. The SD cards seem so small that they could be easily lost.
