Your smartphone has a big, bright, colourful display.  It looks great!

Problem: It consumes lots of power.  And it's almost impossible to read in direct sunlight.

Solution: An E Ink display consumes power only when the displayed image changes & it looks great in sunlight.

But, are you ready to give up all those colours?

Interview with Elon Musk on Tesla Model S performance in cold weather

What happens to electric range in sub-zero temperatures?  Elon Musk says it drops around 10%, but that's mainly due to battery power being used to heat the passenger compartment for the comfort of passengers.

Hint: turn down the space heating, turn up the seat heating & wear driving gloves.  You'll be just as comfortable for a fraction of the energy consumption.

$44.99 — that's a lot less than Canon or Nikon will charge you for a single purpose device with the same or less functionality.

A bargain!

Downside: iOS, only. Bluetooth 4.0 means less battery consumption, but iPhone 4S, or later, required.
