It has to be 'fair and obvious' to the reptilian brain. We are all busy. We don't have time to learn where all the buttons are, what leads to what. I see my elderly parents confused and bewildered. Now I see myself bewildered on new apps that I just don't care to bother to learn. Even Skype - the UI changes so often, every time I use it, I don't know WTF is going on. I can't find how to make the call, put on hold. On my iPhone if I get a call while a call is incoming, I'm immediately pressed to 'MAKE A DECISION NOW!' with a bewildering array of choices while an alarm and buzzer says 'HURRY!'. When am I supposed to learn how all of that works? By 'practising' incoming calls? Technology is exploding, it's becoming too much for all of us - trust me there will come a time where you 'do not give a nut' about learning the UX for the next new thing, and then you're in trouble. Given this I think we need to rethink UI a bit or stick to first principles. And anything that involves privacy or money has to stick to those principles.
