As a bit of a tangent but a note, this is a fantastic article. When I read it in a paper [1] by Alan Kay, I always assumed that most manufacturers would release a full battery that was twice longer than their current size (probably a little bit shorter because it would require a big recharge) in order to support these new models.

I am sorry about this, just wanted to have some fun. I posted the title in the hn comment generator[1] and copied one of the comments here. Guess it passed the Turing test.
