That's a fair point. I do agree with that. There is a human factors issue at play here I feel though (I've worked in aviation industry as an engineer for a number of years and UI is important in consistent controls in a cockpit for example). We are used to dealing with icons in all walks of life - ie navigating to an icon (4 way pad), selecting an icon (what I would prefer to be the OK button), then adjusting a parameter as a result of that step. Pretty much every UI on an electronic device, or a computer follows that paradigm. The model here is perhaps akin to hover over the icon (4 way pad), adjust while hovering, using a different wheel away from the navigational control, go back to the navigational control, and choose OK. It might be because I've come from a Canon, where the Q menu works as you might expect. You can navigate the sections in the Q menu, then you choose OK to highlight the "icon"/parameter, then adjust using scroll wheels. While I'm getting used to it, it causes me to pause to think, rather than being intuitive. There is no need for the OK button to do anything other than affirm the action, rather than cancel the Q menu, as the back button below the navigation pad also performs that, as does touching the shutter button etc.
