CNET have reviewed the Trevor Baylis Eco media player which features a 1.8" screen, and 2 gigabytes of internal memory which holds around 500 songs. 'The Eco Media Player is a chunky little guy that measures 2.5 inches high by 4.5 inches wide by 1.25 inches deep. Don't judge him by his looks, though; the Eco Media Player is designed with utility in mind. Like the Swiss Army Knife of portable human-powered entertainment, the Eco Media Player's design is packed with every imaginable MP3 player feature--and even some features you might not expect on an audio device (flashlight, anyone?).
The Eco Media Player is designed to be used under circumstances where computers and power sources are few and far between. While its fun to think of all kinds of uses for a wind-up MP3 player (bomb shelter, ice fishing, FBI stakeout, mountain climbing, a weekend with the Quakers) more than likely you'll be using the Eco Media Player outdoors. The Eco Media Player's durable design and rubberized exterior reflect its intended use as a rough-and-tumble camping accessory. The Eco Media Player doesn't seem to be any more or less water resistant than an iPod, however, so be sure to keep it dry.'
