The Pebble is a really neat gadget and all, but you can't compare it straight off vs iwatch like that. Pebble has the most primitive SoC bar none in the mobile space period. It's got early 1990s era level of performance and storage. 1-bit paper display. No backlight (unless it's dark). No touchscreen, no sound. Of course the battery's gonna last a week. It's like complaining you have to refuel your Bugatti Veyron a lot more often than your Toyota Prius. (Actually that's a crap analogy, because the Prius is a cutting-edge automobile, but shit, I couldn't think of anything else. Lol. Maybe exchange the Prius for a Volkswagen Beetle?)
