Just like a camera, the best tripod is the one you have with you. There's no point in spending hundreds of dollars on a carbon fibre set of sticks if they're inconvenient to carry. The tiny Tiltpod Mobile is designed to attach to your keys, ensuring it's always close at hand -- or at least somewhere in your pocket.
Given its minuscule dimensions, the Tiltpod Mobile isn't going to handle a DSLR or even a point-and-shoot camera. It's designed exclusively for use with a naked iPhone 4, securing it to any surface with a grippy rubber base, and allowing you to tilt it to almost any angle with a magnetic ball joint. For just $US15 it all but guarantees blur-free low-light shots and perfectly poised time-lapse videos. Since it also keeps your keys secure, it could be the most useful thing in your pocket next to your phone.
