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.The polished c100 series--which reminds us a bit of the Cowon iAudio U3--is aimed at the budget crowd and comes in 1GB (c140, $120) and 2GB (c150, $170) sizes and features a small 1.21-inch color screen. Powered by a single AAA battery, the c100 series is subscription- and photo-friendly, though the screen is tiny, and it includes an FM tuner with 20 presets and FM recording.
