Apple Bluetooth Wireless Mighty Mouse

Pros: It's an attractive glob of white, shiny plastic.

Cons: 1. Within 6 months the scroll ball will need to be cleaned. It can't be cleaned because the mouse can't be opened. So the mouse will fail.
2. The side buttons are an exercise in futility; these are not actually usable in any real sense of the word.

Summary: While Apple might like to believe--or us to believe--that their design philosophy is "form follows function", the evidence suggests the contrary--that the function of their products too often follows the arbitrary forms of their designs.

The Apple Mighty Mouse is attractive, no question, but it's patently unusable.

The greatest design flaw, however, is in the hubris of its design: A mouse scroll wheel WILL become dirty over time, and this necessitates cleaning it. But the Mighty Mouse cannot be opened, and therefore cannot be cleaned, and so it cannot be used, and fails as a product design.

I'm getting the sense that Apple engineers design in a vacuum, and that when the decision arises to choose a little more beauty over a little less functionality, they jump at the chance, eager to push the ergo-ego boundary.
