The e-paper watch ($150) made huge waves after raising a record-breaking $10 million on Kickstarter (the goal was only $100K). The watch was so covetable that units hit shelves at Best Buy to help meet demand.
Pebble pairs to a smartphone via Bluetooth and, like most smartwatches, will receive text/email/call push notifications. It also works with activity apps like RunKeeper and FreeCaddie. The difference is that Pebble, which was one of our top picks for Father's Day, uses a battery-saving, black and white e-paper display that looks great in bright sunlight.
