Skypephone / mouse combo:

This mousephone from Sony (Japan) is a step towards what I've posted about on different occasions, which is basically that handsets are becoming more of a true TCB than smartcards or Palms ever will.

What's added by this is that the clamshell design is obviously a great way to hide the "phone" nature of the chunk of plastic when it's not being used in that manner. Smart thinking. Apple, your iPhone should do this.
