Slacker Internet radio is going portable!  Slacker offers free, sponsored Internet radio with 1 to 2 minutes of interstitial ads per hour.  In its free service, Slacker allows 6 skips per hour per station, but with over 100 genre stations to be listened to (working out to the ability to skip 600 songs per hour), even the most skip-happy listener can satisfy their urge to get to the next song quickly.  Slacker’s Premium membership offers unlimited skips and saving and replaying favorite songs starting at $7.50/month.

Slacker Portable is Slacker’s companion personal media player.  Available in 2, 4 and 8 gig models (translated to 15, 25 and 45 stations), Slacker Portable fills itself from the user’s favorite stations every time it’s synced.  Not only is the music on the player, but anything available from Slacker’s site is available on the Slacker Portable, including artist bios, reviews and album art.  Because Slacker Portable isn’t constantly connected to Slacker’s HQ, there’s no cutout when a listener enters a subway train, goes into a tunnel, or anywhere that a signal would be lost with an FM or a satellite radio.  And if you can’t live without that certain album at your disposal at all times, Slacker Portable allows you to load mp3’s from your own library.
