Apple allowing developers to adjust their apps to fit the Apple Watch
According to an unnamed source who was present for some of the testing, Apple goes out of its way to keep things secret, especially when it has non-Apple personnel in contact with a device that has yet to launch. The rooms had absolutely no internet connection and outside materials were not allowed in.
While Apple CEO Tim Cook has said that the Apple Watch won't be released before April, a media event is scheduled for Monday that will apparently focus on Apple's new timepiece. We should learn the answer to some unanswered questions such as the pricing for the mid-range and high-end models, actual battery life, and an official launch date.
