Let the hive mind of Engadget get that for you.
"For a long time I have been searching for a portable device where I can store all of my CDs in MP3 format and stream the songs wirelessly to my HiFi system. The portable device must I've tried FM transmitters, they all suck. I don't want a docking station. Any help? Thanks!" have a display so that I easily can scroll through the playlists (I don't want to use a TV or monitor). I suppose that there must also be a second device that is connected to the HiFi system that would receive the wireless streams from the portable device.
Firstly... a lot of people read this post incorrectly. Sony is looking to sell the ability to harness users PS3's to companies that want to use it for their own benefit... not for NPO like Folding@Home. If this was to go through you would be helping random companies like Chevron calculate deep-sea oil drilling sites and helping the CIA calculate the location for their latest illegal detention center (what?). The supposed upside for users that donate their PS3s to this money making scheme is that thye get coupons or prizes.
Other than mentioning Folding@Home once in this post... it has nothing to do with that humanitarian project. Please learn to read.. and if you can do that.. then at least learn to understand what you have read.
