vibration and geolocation add value in very different ways

[chaals]

There is one example in "add value" that includes both of these. It is unclear what value location based services might add in the first place, but also they are two pretty different approaches.

Vibration is clearly explained as a direct benefit. geolocation isn't. I would just remove it, or move it to a seperate example that explains some concrete value.
