Memory goliath SanDisk continues its assault on the flash-based MP3 player market with the launch of the flagship e200 series and the budget-class c100 series. The sharp-looking e200 measures 3.5 by 1.7 by 0.5 inches and has a maximum capacity of 6GB ($300). It boasts a photo- and video-friendly 1.8-inch color screen, as well as a durable titanium back cover and a user-removable rechargeable battery. The e200 also comes in $250 4GB and $200 2GB varieties, while the 6GB version is notable, as it's the highest-capacity flash-based player in the world. Other cool features include a MicroSD expansion slot, slide-show functionality, an FM tuner with FM recording, and compatibility with WMA subscription services. The players, which are physically much more finished than SanDisk players of the past but, with price tags to match, will be available in March.
