The photos in those things are awful. Tiny black and white pictures with little context or detail.

Why do we not have tablet apps which allow you to see how everything fits together, how the drivetrain redistributes energy, etc?

I agree, found some content I really like.

I think that's a neat idea, but I personally would be nervous about smearing grease all over my tablet, or spilling fluids on it, or dropping it -- something that happens to almost every other tool at one point or another.

As a reference away from the garage, it would be cool, but I would still want something I would feel safe having by my side as I work on the car.
