Pebble took the start-up world by storm with its introduction of the first contemporary smartwatch as we know it. Having already pushed over 300,000 units, the company has faced pressure from the likes of Sony and Samsung, but so far - and largely due to the ineptness of the aforementioned - Pebble has weathered the storm. Today, as promised, the company has rolled out its tailored Pebble appstore as part of its version 2.0 firmware and iPhone app to reinforce its position in the smartwatch market.
