A modern Pebble would be very interesting. An e-paper display smartwatch that runs whatever I want it to would be great, with the benefits of modern batteries and e-paper. Maybe use those advancements to build it cheaper so I could have a smartwatch that does the things I need (text message display, media control) which being cheap enough I don't have to be constantly scared of breaking it while doing manual labor.

If enough people are interested, we'll build it

I'd remove that line from the website. That's a line from a bad Kickstarter.
