An anonymous tipster sent us a bunch of pictures he shot last night from the outside of the Saturn Cafe in Santa Cruz. While we don't normally toss up random pics we get in the tip jar, this guy claims the pics depict the filming of a commercial of a possible "iPod killer" from Microsoft. We can't vouch for the validity of this, or for this guy's camera steadying abilities, but there does appear to be something going on here. The device's screen ratio reminds us of the Gigabeat S, so Portable Media Center seems likely. Keep reading for even more nauseatingly blurry pictures of the device.
