Have a party in your pants.
No, seriously, thanks to Sirius’s S50. The roughly two-by-four-inch color display-equipped mobile jukebox (featuring MP3/WMA song compatibility and a built-in satellite radio tuner) fits neatly into any pocket. Connect with a home/car dock and store 50 hours of commercial-free, uncensored programming via 30 channel presets, or enjoy voice-assisted navigation and automatic recording functions. $360. www.sirius.com
