When the original iPhone was getting released, it was a big investment and I wasn’t sure whether I’d get one or not. Then just a few days before launch Apple released this video and I was hooked. Showing us exactly how the revolutionary phone worked was brilliant and, in my case at least, sold one more iPhone. Apple is going back to the same playbook with a series of guided tours on the Apple Watch. So far there are only three videos available but there are at least seven more that will unlock between now and launch.

My favorite so far is the second video, on faces. Another observation is that in the third video, on digital touch, it looks like a 42mm watch on a slender wrist and it looks pretty big.
