Soft Cell

Here is incontrovertible proof that just because something is technologically feasible doesn't mean that it's even remotely a good idea--a Bluetooth-enabled pillow:

The perCushion...a cotton velvet pillow with a Bluetooth transceiver inside. Just place your cellphone within 30 feet and you can engage in a little pillow talk with your significant other.

I wonder how well it would hold up during a pillow fight.
