I think if EVE could make a variant of the V with a foldable OLED screen, which would leave the workable dimensions of the V similar to what it is today but shrink the closed size of the V half of the footprint, that would be phenomenal. Of course, the keyboard would be one of the big problems to resolve, but using the folding technology making its way to phones would be interesting. It would require inclusion of the next topic listed below, namely solid state lithium batteries, which would dramatically change the power characteristics of the V.
I have been writing quite a bit lately (I am in the final stages of publishing my book, “Thriving with Information in the Digital Economy”, and one of the things I have been covering is the metamorphosis about to occur in battery technology, namely the first one probably being solid state lithium batteries (other technologies coming up through the ranks are Graphene capacitors (I don’t know why they aren’t called batteries, but they aren’t) and Sodium Carbide batteries). The capacity of solid state lithium batteries is 2 - 3 x of lithium ion batteries and don’t have the characteristic of ignition or explosion as witnessed with the Samsung 7. Being an early adopter of such a power source would bring very interesting capabilities to a future V.
