Apple doesn't want you to spend a lot of time with Watch apps. Specifically, if you're looking at your Cupertino-device adorned wrist for more than 10 seconds, that isn't ideal according to Bloomberg's sources. In addition to quick bursts of info, Watch apps also use location services, among other features, to keep the amount of distractions to a minimum so your wrist won't constantly buzz. For instance, saving specific personal email alerts until you're home from work. From the sounds of it, that should serve a few different purposes: conserving battery life and keeping annoyance levels down. The former of course is a common complaint lobbed at most smartwatches thus far.
Bloomberg also reports that, surprising absolutely no one, the company's hoping to keep a tight lid on the gizmo's particulars ahead of its big reveal. How far's it going? Glad you asked. The Watch test lab is apparently locked down from outside communications: there's no internet access and app developers can't even bring in their own paper to work from. This is in addition to Apple requiring that any source code be brought in on hard drives that can't leave Cupertino HQ. Bloomberg's anonymous sources also report that Cook and Co. are storing said code onsite and, to ward off any leaks, won't redistribute it until closer to Watch's "introduction date." Given that Apple's holding an event on Monday, that could be sooner rather than later.
