After years of rumors, leaks, and false starts, it seems the stars are finally swinging into alignment this fall: Apple is now expected to unveil an iWatch smartwatch alongside its new large-screen iPhone 6 at an event on September 9. Presumably the iWatch would also be released alongside the iPhone 6, a week or two later. Previous rumors had pointed to an October unveil for the iWatch, but it seems Apple has moved it forward -- possibly in response to the Samsung Gear S, LG G Watch R, and the Moto 360, all of which will be released over the next month or two. Just as the iPhone and iPad popularized the smartphone and tablet, will the arrival of the iWatch signal the beginning of the wearable computing revolution?
