Is it possible yet to Miracast from the Pi to a smart TV? I like the form factor, but I'd love to only be tethered to power and not HDMI.

Kindof same... but for me it's frustrating that they don't include any sort of mouse device, which negates the "all in one" of it.

Too much on Linux (and websites!) expect mouse-style input, so.... you have to have a mouse, the stupid HDMI adapter, etc...

It's almost a better form factor to use a regular pi paired with the Logitech keyboard + trackpad setups. You can almost treat the pi as if it were an inline power brick.

The alternative (that I haven't quite gotten around to trying yet) is to use one of the "use your phone as a mouse" apps, basically it installs a mouse-listener-over-WiFi and then at least you can emergency-browse with the "just a computer in a keyboard" setup.
