I work for myself <a href=" http://levitracostcomparison20mg.xyz/ ">levitra 20 mg best price </a> But the potential of a brewing rivalry between SmartThings and Nest raises an interesting possibility about the shape of the programmable world. Phones, for instance, are split between by two rival platforms, Apple&#8217;s iOS and Google&#8217;s Android. Nest is a closed, proprietary ecosystem built with meticulous design and care; SmartThings is open-source, so anyone can develop products within its platform. It&#8217;s all too easy to imagine that, just as today we are unable to send a friend on Android an Apple iMessage, we might at some point talk about our home as a &#8220;Nest,&#8221; while a friend&#8217;s house is the land of SmartThings. And, somehow, the idea of debating about which company&#8217;s ecosystem controls our home seems even more depressing than arguing over our phones.
