I didn't really understand the utility until I watched Casey Neistat's video of using it in public as a portable entertainment experience device. If it gets down to a lower pricepoint I can definitely imagine people using it on public transport and the like to watch netflix on their commute. People will definitely want to use it that way, because that's a totally novel use case. If it gets down to $1000 and is portable enough, you will see people using it extensively in public. I don't think Apple intend for that yet though.
