I think a really cool idea would be to have a strip of e-ink on the side of e-cig batteries. A way of indicating how much you've vaped in relation to an analog cigarette. When the strip reads full it's the equal of a full analog. When it reads empty, you've just finished the equivalent of an analog.
This system would definitely work better for pre-filled cartomizers like you find on the KR808D1. But even then those carts would have to communicate with the battery and have to be able to judge how long the drag is off of them. The longer the drag the further the status bar goes down. Just like the longer the drag on an analog the further the analog burns down.
But overall e-ink is coming down in price and a small strip on the side of a battery wouldn't draw much power from the battery itself. The nice thing about e-ink is that it only uses power when it changes its state, so when you aren't dragging on the e-cig the indicator will always show the level you're at. Now if you pop a different cart on, that new cart will have to refresh that e-ink strip. Which means that cart has to remember which level it was at. Think of it like smoking half a cigarette and then lighting up a new cigarette and then finishing the other half of the first. The side benefit to that is that it can also remember how many analog equals it has gone through, which means you could get a read out of just how used up that cart really is.
But the biggest benefit is that is gives people a way to judge how much they're vaping in a day.
