If you've been working out with help from tunes on your Sansa Clip MP3 player or Sansa Clip+, chances are you've gotten a bit trimmer -- and you're not the only one. SanDisk's launched a thinner and upgraded version of its song slinger, the Sansa Clip Zip MP3 player. The newest incarnation plays all standard major music formats, comes in red, blue, black, orange, white, grey and purple, and has 4GB or 8GB worth of storage with room for more via microSD. It's launching in Europe next month, but is currently available in both the US and Canada for $50 and $70 depending upon how many jams you want it to hold. Thanks to its massive 1.1-inch display, the Clip claims 15 hours of battery life, which should be just enough time to keep up with your daily workouts, right? Jog on over to the full PR after the break.
