Remember the iPosture? That little button-sized nano-sensor you attach to your body which then vibrates any time you slouch or strike a less-than-optimal pose? The one which supposedly improves your posture, making you look thinner and taller, feel more confident, and also doubles as a hot piece of jewelry? Well, it's available now for the pretty reasonable price of $89.95 with a free copy of "Young, Sexy and Healthy" -- which you were probably considering buying anyway. If you're one of those people who can never get enough of being nagged at over your seemingly minuscule flaws, this just may be the perfect device for you.
