I can't be more excited about the WATCH. Apple has added a massive improvement to WatchKit this week - the ability to open up the iOS App from the Watch. We can expect more to come in January before the WATCH is actually released "early in 2015". But I'll be honest, all the App Store rejection stories of Extensions (aka Widgets) are not very encouraging when it comes to what kind of WATCH apps we're expected to build.
I'm worried that devs who are "too creative" with taking advantage of the WATCH platform will be rejected. It's an exciting platform, and we all get to be first to develop for it, but it's unclear whether Apple will allow us to build things beyond their vision and expectations.
