M2 is a format jointly developed by Sandisk and Sony and in real terms, 4GB is around 1,000 MP3 tracks – giving many standalone MP3 players a run for their money. Alternatively, it’s also enough for 2,000 high-resolution images or 20 hours of MPEG-4 video. The card is compatible with Sony’s latest multimedia handsets, including the recent Cyber-shot and Walkman phones.
According to Norm Frentz, director of marketing for SanDisk’s mobile consumer solutions division. “This is the threshold at which mobile phones provide enough capacity to become the user’s all-in-one portable music player, camcorder, photo album and video player.”
The 4GB M2 card will ship in May, price to be confirmed,
