You people are missing the point. It's tiny computer that is cheap enough for a lot of projects that have zero need for a display. At the consumer level, you can have a 9$ web server or a 9$ torrent box, a 9$ controller for cameras or for automated irrigation...
Also, the RPI had shitty USB, hence shitty wifi for ages. I think they fixed it in the new revision.
As for the Pandora, it had a good price when it was announced. There still isn't anything that does the same so well, though a cell phone with a controller is ok too, but you can't match the controller and keyboard. I'm happy to have had one since launch.
