Hookai. So. The Samurai Air Sword is really an iPhone in disguise. It doesn't come with touchscreen, CPU, multimedia processor, memory, GPS, or compass. But it has a gyroscope and runs a clone of the only iPhone application that matters.
The Lightsaber app! Except it's not really an app, and this is better: It makes 48 swooshabolous sound effects while you move it up in the air using a motion sensor. So screw the web browser, the mail, the stupid touchscreen, and all that fancy crap. For $18 and two AAA batteries, this thing does exactly what you need it to do. [Happinet via IT Media via DVICE]
