Amazon Kindle

The nice thing about the Kindle is that, like the original iPod, have one function.

it's nice to have a device where you can read a book in, and treat it as such, it's pretty rare for a product to have a single function in our world of muilt-functional gadget that wipe your arse as well as ringing the doorbell.

You know what I just figured out... If you turn it face down, it has zero useable functions. This thing is ticking all the boxes for me.
