Other than initial teething issues I´ve not had a single hardware related problem with my setup. Starts up on it´s own, comes up, drive off, turn car off, shuts-down. IMO far more reliable than most head-units I´ve had in the past, and/or installed.
Plan on an HDTV usb adapter shortly, while craptacular as I understand it rolling down the road, should be good for when I´m just sitting somewhere for a bit to drink my coffee and watch a bit of something and the like. I get all I could really ask for options wise, with the ability to do a hell of a lot more, and it´s been rock solid.
