Samsung Galaxy S can download an interesting little app. Called Road SMS, the basic idea is that the phone's camera constantly runs to let you see through the screen, while a virtual keyboard allows your fingers to safely text whomever you want. Needless to say, it's a very bad idea for number of reasons -- not least of which the fact that thumbs will always obscure the screen -- but we'll leave discussion of the pros and cons for the comments below. To be frank, we don't think folks will use this app seriously. We're just hoping someone will develop an augmented reality joke version that, ever so often, generates ghostly images of high speed oncoming traffic. And remember kids, don't text and drive.
