SanDisk this week announced it will add an 8 GB model to its Sansa e200 line of MP3 players. With the actual launch, in September, the company will offer double the capacity of the top iPod nano (4 GB) for the same price (USD 250). Like its siblings, the e280 measures 1.7x3.5x0.5 inches (4.4x8.9x.1.3 cm) and sports a 1.8-inch TFT color screen. It also has video playback capability, FM tuner, voice recorder and a microSD expansion slot, for up to 2 GB of additional memory.
