With all the lights that adorn modern notebooks, it's truly a shame that most of them aren't at all useful. One modder, sharing this philosophy, added a 3-color LED to an Asus Eee 901 to track incoming messages.

Combined with an extra microprocessor and some custom scripts, the RGB LED illuminates with a different color depending on whether it's email, an IM or a new tweet awaiting one's perusal. With as much extraneous bundled hardware and software bloats most laptops, you'd think someone like HP or Dell would simply integrate such luminescent feedback into their complete line. You'd think.
