This is awesome!  You no longer need to worry about the positive and negative poles and where they belong in the device you are installing it on.  We need this in every device, even as we go rechargable.  I would rather have them recharable, but since it will take time to do that completely (and safely for the environment), I want more of this.

It is not a huge inconvenience to figure out the batteries, but I have to say this is a fun technology that should have been invented years ago.  I don’t understand why it wasn’t invented years ago.  But, it is here now and we can all thank Microsoft.
