Text while you walk with Road SMS app
Many apps are badly made and utterly pointless. However, one has come along which looks genuinely brilliant and insultingly simple in concept and use.
The Samsung App Store has this ace thing called Road SMS, which is an Android app allowed you to see where you're going while walking around sending a text. Basically, it uses your camera and lets you peer through the display, ensuring that you won't walk into a lamp post or, more importantly, dawdle so much that you make the person behind you want to kill you dead.
For the time being, it looks like an exclusive for Samsung (and comes pre-installed in the Galaxy S i9000) but it won't be long before it is spread across all the Android markets or, maybe, ripped off by someone else. What a devilishly good idea!
