There are definitely things the Spotify Car Thing could've done.
It's a potato, sure, but there are still uses. Displaying some PC information, weather information, using it as a macro-pad (someone actually did that one)... or doing the thing it was designed to do: show some album art and the song you're playing, and giving play/pause, skip buttons.
Shit, even a desk clock would be better than nothing.
E: ah, I see you said unlike, not like. Never mind.
