> I can't see any realistic way that the ergonomics would be better than your haphazard hotel room setup
Looking down onto your lap sucks over time. Resting your head (pillow or other head support) while wearing AVP vs. holding it up is the key to using AVP for better ergonomics compared to using just the laptop.
I'm thinking of trying to make a DIY easy rig for holding it up from a backpack mount above my head like this: https://youtu.be/o_guGeVboRg?t=75 (but with lighter weight parts because it's not as heavy as a serious camera)
