SanDisk has been trying to get a piece of the iPod pie since the introduction of their Sansa series, although the response has been lukewarm at best. By teaming up with Yahoo, the two companies have found a way to compete against Microsoft's Zune and ostensibly, Apple's iPod. This player is very sensitive to the adoption of Wi-Fi networks so the market is currently pretty small, although this is set to grown in the next year.
