Delphi has officially launched the portable XM receiver it quietly announced last month. Marketed as "the first Micro SD Compatible MP3 Satellite Radio" the SkyFi3 is a lightweight unit (65 percent smaller than the SkyFi2) with a built-in receiver that can be used in concert with the Live Wearable "antenna" headphones (a $49 accessory) for true portability. It's near impossible to track down a photo of these 'phones (I've tried here and here), (probably because they're big and dorky). The SkiFi3 sports a bright 9-line 2.8-inch display, and vertical and horizontal flexibility, is ideal for car use. It ships with a car dock kit and will be available December 1 for $229. The device can record up to 10 hours of satellite radio and store songs in the unit's built-in flash, and it includes a Micro SD slot that allows you to play back MP3 and WMA files. Like the SkyFi2, this version can pause live recording and rewind 30 minutes of content. Additionally, the SkyFi3 features a strong FM transmitter.
