What is your favorite technology?

My favorite would have to be interacting with computers or other devices with your brain. There's a company that will soon (within the next month or two) start selling their Emotiv Epoc headset that recognizes 14 cognitive states (such as up, down, left, disappear, push, etc.), emotional states, and facial positions. With this kind of technology the immobile can move and the mute can speak (Well, sort of. They place electrodes on the neck I believe, and the nerve signals to the vocal cords can be picked up. But it works and uses the same technology). It's going to be interesting to see what kind of applications pop up from this brain interface technology in the future. (For the record, the headset is $300.00, comes with a game to hone your mental abilities, a wireless headset, and a bunch of software, including software to map thought patterns to key presses so you can use the headset in existing applications. And yes, I plan on buying one. ;))

my favorite technology is the one where you can hit cntrl f on your computer and it will find any word that currently appears on your page. this is crucial when trying to do homework on pdf files or when you are searching for good discussions on mylot
