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.
Here's a fundamental patent concept that may help: patents give you the right to stop someone else from doing what you teach in the patent for some period of time. They do not give you the right to do something. See the difference? If I have a patent that teaches X, and you start doing X, I can sue you to make you stop and/or pay me. It doesn't matter if you have a patent that seems to say you can do X as well. So it is just as likely that Apple patents technology to make sure others can't do what it has no intention of doing as it is that they intend to do that thing.
There, I feel better.
