Query: A decent design, but ...

The Rio Riot is a product that, to be blunt, needed about three more months of solid testing and "fixing" before being released. One of my biggest complaints, and one that isn't addressed much in others' reviews, has to do with battery charging.To begin with, the battery doesn't charge at all unless the player is turned on. (This is mentioned briefly in one of the paper "read me" documents in the box, but not in the manual itself.)What's worse, though, is that it the player doesn't hold its charge. A fully-charged player, turned off and sitting for about a day, loses roughly 20% of that charge. Leave it for a week, and you'd better plan on doing a full recharge before taking it anywhere, because it won't last an hour.Given the big price, the terrible software it ships with, and the alternatives in the market (including the iPod and the new Nomad), I couldn't recommend the Riot to a friend.
