IMO it would be awesome if it also exposed an ACM serial device so that one could connect with a terminal emulator and avoid fiddling with SSH.

Otherwise this is very cool.

The BeagleBoard was awesome at it's out of box experience. Connect it to a computer & a network interface shows up. ZeroConf advertises a webserver. The page is a web based IDE for programming the beagleboard.

USB gadget remains such a great fan favorite. Peripherals affording your main computer the option to do more is sweet, and that rpi & others can offer up their services as so is sweet.
