First word of an alliance between Samsung and XM crossed our desktop in July. And after a brief gestation the neXus is born. This is Samsung's first MP3 player with XM Satellite Radio readiness. It comes in 512MB and 1GB capacities and includes a home docking kit for listening live while at home. That's right: Just as with the Sirius S50, the neXus does not offer true XM portability—just the ability to capture and store the sat-casts. Available sometime in the fall.
