Well now that is hardly the burn you think it is, isn't it?
To compare it to reading a book is really not understanding how reading a book works.
When I read I pick up a book and start… reading. Immersed but still able to be aware of my husband's intermittent conversation with me, stretch my eyes by looking out the window, that little pause to think over something you've just read, stroke the cat, hear the doorbell and answer it — pick up the book again — put down the book, go have a pee, answer my phone — listen to music…
What I don't have to do is strap a humungous self isolating device on to my face and then sit there, apparently immersed in my own little universe.
This AVP device is first and foremost a device that will further isolate people.
Or do you self isolate in a sound proof room when you go and *read a book*?
But, then again, YMMV and you do. In which case the AVP is probably perfect for you.
