Really, I thought Hugo had said the HSX hardware was based on the empeg in another thread. What is different about it aside from support for the extra peripherals?

Well, looking at it one way, there's little difference except for the "extra peripherals". But as the extra peripherals include a bigger screen (and attendant richer UI), USB host, CDRW, etc., that is in fact rather a lot. An HSX player binary is about twice the size of a car-player one, and there's no way you could run all those extra features on a car Mk2. Apart from anything else, the HSX needn't keep its disk spun down like a car player does -- so it can swap.
