Every so often I bump into yet another example of Linux being used in creative ways. Here's a new one: an ASUSTek motherboard, the P5E3, which ships with a built-in Linux variant called Splashtop.
Splashtop's a small but fairly useful Linux desktop environment that boots and runs entirely in RAM. The current iteration of Splashtop features network connectivity (both wired and wireless), a rebadged version of Firefox 2.0, and the Skype VoIP client (version 1.3) -- a small but useful clutch of tools. I read through a sneak preview of the product at Phoronix.com, and the impression I got was that it's still pretty rudimentary but that it will over time be expanded into something far more functional.
