I meant to write a very exited blog about the new iPhone 4 having a gyro, which I thought would really advance the options to get indoor nav on your smartphone. It turns out there are $1 gyros and $7 gyros. Guess which one is in the iPhone and which one is useful for navigation…
The demand for gyros pushed by the iPhone4 definitely means that the prices are coming down, but let's wait a few years to see how quickly and strongly mobile gyro nav is adopted. In the meantime, trust Layar to show us what gyros can enable on a smartphone (and on the forthcoming Nintendo 3DS).
