Hi Jim,
whats the diff between the remote your selling and the one that came with my S800?
hmm, IIRC its compatible to S800. its backlit, so when you accidentally sit on it , or when you use it, the buttons light up so its good for low light rooms.
I just like the feel coz its much like my PCH C200 remote. the Next chapter / Previous chapter button is switched when using with egreat, but its really minor.
