Thanks to global warming, you needn't spend a fortune on a personal media player to make an impression, at least on the West Coast. In fact, your PMP can even be kind of clunky and not pack the most impressive features. It just has to be green.
Few can make that claim better than eMotion's solar-powered player, which was first shown at CES in January but is now available for purchase at $169. Inventor Spot wasn't terribly impressed with its specs--especially storage, or lack thereof--but how many times do you need to watch An Inconvenient Truth anyway? Besides, you can play some old-school Sega games on it for the full retro-treehugger effect.
