Depending on your perspective, the Apple Watch has been a great success or a big flop. While Apple has sold more smartwatches than any other vendor, it hasn't lived up to the hype or its potential. The battery life, bulk, and performance all need work, and while Apple hasn't released a new physical device, at today's Worldwide Developers Conference, it did announce a new version of watchOS, dubbed watchOS 3. It should improve the battery life and performance, but it will take a new device to improve the bulk.
