In all the smartwatch reviews I have read, I fail to see the high-level overview: what kinds of tasks should I be able to accomplish with this kind of device, at all?<p>Are Android Wear devices only usable in a vicinity of my Android phone or can I use them without one? Could I use them with an iPhone, Firefox OS phone, Surface Pro tablet, 3G modem or any Wi-Fi source (Moto 360 does have Wi-Fi)?<p>Do Android Wear devices need apps written specifically for them, and/or specific support in a tablet/phone app. Say, I know there is a VK app for Android, but I'm not sure about smartwatch support. Should I be getting VK notifications (or whatever watch is good for) by default?<p>Could I pair a Wi-Fi-equipped smartwatch with a Bluetooth headset and get rid of a phone, with smartwatch providing VoIP connectivity over Wi-Fi?<p>What kinds (if any) of non-default configurations can I expect to use a device like that? (default being pairing it with an Android phone and a specifically supported app)
