Google Glass, the latest eyewear trend wants more Glassware. Google now offers developers the Glass Development Kit and the Mirror API, altough the latter one is a rather limited tool. Nevertheless, the Mirror API has some unique benefits. For a higher degree of flexibility, devs can use both tools to get the best of both worlds.
Previously, only a few developers had access to the Mirror API. With the new policy, Glassware will expand providing customers with lots more apps to choose from. Glassware is a very young app niche with lots of potential and very appealing for developers who want a brand new environment to expand their ideas.
