SanDisk unveiled the world’s largest capacity flash-based MP3 player, the 8-gigabyte Sansa e280 that boasts award-winning audio, photo viewing and video clip playback capabilities. Priced at $249.99, the e280 is the latest evolution of SanDisk’s flagship e200 series. The 8GB device sports a microSD expansion slot allowing expansion to 10GB of music–or 2,500 songs–with an optional SanDisk 2GB microSD card, making it the largest capacity flash-based MP3 player on the market. In conjunction with the rollout of the e280 and in preparation for the holiday season, SanDisk has lowered its prices on the entire Sansa e200 line of products, including the existing 2, 4, and 6GB models.
