Seen a guy with one of these last week, and whilst they look nice, IMO they are too big and chunky to use as a daily carry around player, and they look very delicate for taking to the gym etc.
Indeed, weird cartoon thing he was watching... In terms of looks there is no comparison, the touch is leaps and bounds ahead of the Archos IMO and is a lot more friendly in terms of size for it to be used as a true portable player the Archos looks akin to Red Dwarf technology.
That said, both of them are amazing products so either player you are getting is bound to give you hours of enjoyment.
