In a decade the hardware may fail (yay today's manufacturing practices). But in 2-3 years, most Pebble fans will probably have broken their current watch, and will be desperately looking for replacement. Since among smartwatches, Pebble was the single least shitty option (by a wide margin) and no company is stepping up with a comparable alternative, people might pay good money to get a working one. I know I probably will.
