I am a HTC/Android user, and have heard good things re Google / android TV. I am considering purchasing a USB-HDMI version. Is this ok, or is a box better? I assume the usb is wifi, and boxes be either? Should I be going for Android 2.3/4.0/4.1, or are they all easily upgradeable? Will it stream media from PC? Might it have a port to add an HDD for recording? Can this be done to PC (maybe if wired to/thru router)? Best way to control it.....I don't want a TV type control....I would like as similar to a mouse as possible....I've seen the Rii R900 (link not aloowed as a newbie!), any other out there? How can I find what channels I can stream etc? Or is this done by Apps on the google play?
