I really don't understand much in this, but it seems that one of the really cool things that happens these days in the gadgets world is that the price of all kinds of sensors really dropped to the floor.
In the past year I suddenly started to see more and more products with cool sensors capabilities.
For example: I just bought the new Microsoft Wireless keyboard for my living room. Besides the fact that it is designed really beautifully, the really cool feature of it is in the sensors built in into the keyboard.
Whenever you get close to it, the keyboard "sense" it and lights up with backlit so you will be able to use it in the dark. It's even getting better. This actually happens just if the room is actually dark, so in broad day light the keyboard won't light up and save up on the batteries.
You can see similar behavior in other products like the iPhone or many of the new tech toys out there... It's a brave new and cool world our there...
