I've seen this in the apps section, and how wondered just how useful this is?

There's a couple of iphone products that are cheaper. The calculations behind the scenes are pretty simple and the hardware's all the same, obviously, so it basically comes down to preferred user interface and features.

BTW, there's also an OBDII code reader for the iphone.
