oh.. my bad.
I have a cell phone that is bluetooth enabled. I recently found out that in the near future I will be able to - through my cell phone - unlock and lock the doors, lower and raise the windows, remotely start, and open the trunk of my car.
That is the power of bluetooth!
We do many things through radio frequencies, bluetooth takes it to another level. Being able to use multiple devices at home or in an office WITHOUT wires getting in the way, is virtually priceless (in my humble opinion). Bluetooth works with keyboards & mice and printers & fax machines at home or at work. (A retail store my company help set up, we used HP PDA's to gather and store information ranging from what aisle products need to be moved to.. to daily sales and labor reports and inventory all with bluetooth technology)
Infrared used to be the wireless way.. but that is LINE OF SIGHT... bluetooth is the future of wireless interaction.
