Why its taken so long to get MP3 players with wireless capabilities, Ill never understand, but Im glad to see the trend finally emerging with this year's CES announcements. While Slackers player delivers custom radio stations, Haier is going after the podcast crowd (is there still a podcast crowd?). The ibiza Rhapsody player starts at $200 and automatically updates your podcast subscriptions anytime youre near a Wi-Fi hotspot. A small thing, maybe, but at least it's another weapon in the battle against cable clutter.—Mike Haney

When Slacker first started talking about a wireless MP3 player that would learn your preferences in music and build you custom radio stations, the idea was awesome. Then more than a year passed and still no player. Meanwhile, services like Pandora and Last.fm built huge fan bases offering similar services. Now the player is finally here, debuting at CES, and the idea is no less awesome. The device will come in three capacities: a $200 2-gigabyte model that will hold 15 stations; a $250, 25-station 4-gigabyte; and a $300 40-station 8-gigabyte. You can set up your stations from any browser—so the device isnt locked to one computer—then anytime youre near a Wi-Fi connection it will automatically load enough songs (with cover art) to keep your stations going for several hours. You can also load your own music files on it, although that will take space from the stations. And because the music isnt streaming, quality shouldnt be a issue. Well be taking the device for a test drive at the show and let you know if the reality is as great as the promise. Whether Slacker succeeds or not, Ill be shocked if Apple doesnt incorporate something like this into the next generation of iPhones and iPods.—Mike Haney
