Orbitcast has posted photos of the newest portable XM Radio player, the Pioneer Inno. The iPod-sized device receives XM's live signal, records up to 50 hours of music, schedules recordings, and plays WMA's and MP3's. Like earlier XM portables, the Inno has a built-in FM transmitter, allowing you to play your satellite radio over analog radio. Nice. Other specs: color display, 50 channel presets, playlist editing on the device, 5 hours of live XM playback and 15 hours of recorded playback. The price? A mere $399. The Samsung Helix, listed on the XM site as having the same features, is, according to our sister (brother? kinsman?) site, Engadget, nowhere to be seen and XM does not list a price. The Samsung Nexus, available on pre-order, is available in two flavors, 25 and 50 hours of recording time. But - dealbreaker! - they only receive XM signals while docked. Listing at $219 and $269, respectively, the pair of Nexus's (Nexae?) are billed as the world's smallest XM radios.
