Here's a terrific little iPad hack that occupies a niche that would otherwise be filled by a single-purpose/specialty device...

iPad integrated into kitchen cupboard

It would be nice to have a waterproof bluetooth 5-way navigation device mounted to your kitchen counter as well. That way you could actually operate a specific app (with support for that device) with your hands dirty - and then wash the controller.

A perfect example of using an iPad as a dedicated-task device. Of course even though the application can be considered dedicated (built-in) the iPad's OS itself offers a tremendous amount of content variety should you ever want it.

This is why it would otherwise be so easy to deploy 10 or 20 of these things in your personal and/or professional life.
