There is at least one good reason to use AVP in public; alas, even I am too self-concious to do it
I am attending a medical conference in Valencia, Spain this week — more thoughts on being back in Europe after 7 years coming up — and all I could think about while sitting in the auditorium, looking at slides and listening to the speakers was that these kinds of events would be the perfect use case for AVP. The congress center in Valencia is top-notch, with comfortable seats and plenty of leg room.
