Tactile feedback and consistent UIs are great and a common feature (if not a defining one). I've got a Pentax dSLR -- it's got an excellent UI (better than canon's, imo) and their manual tweak focus adjustment & focus hold system does just work very well. It also has an excellent set of manual controls. A pity that nobody else has heard of them...
