I still think it's worth something. It was a damm fine player, the interface is great, and I really liked the 2 handed feel when on long trips, it's a shame there wasn't some sort of tetris type game on it, they it would have been perfect. I love my Riot almost as much as my Karma (still going strog, never missed a beat).
I have collected a few Riots in attempts to keep mine going, I even have a development one from Hugo, although I'm not taking that part for spares!

If you are going to throw it away then I will cover the cost of postage to the UK, otherwise why not put it on eBay if it still works it's got to be worth something.
Cheers
Cris.
