OK I recently switched to mac mini after buying a nano. Been in the Sacramento store a few times and have experienced most of the above. Was completely frosted about not being able to make an appt. at the genius bar, just bring it in, and then told it would be a 4-5 hour wait. Over New Year break I got a few accys. and stood in line 30 min.OK they were very busy I understand. When finally at the counter in asked if their overpriced a/v cable would work with my nano it does say on the box works with all color displays but I wanted to be sure having bought a camera connector (same labeling) that didn't) Her immediate response was yes, very confident. 2 days later to return I stand in another real long line to be told it sure does work w/the nano, The 3rd guy knew that the nano doesn't have a video out. Great product knowledge!
