Virtual Keyboard amazes, but does it make sense?

Computerworld - The iTech Bluetooth Virtual Keyboard is a little black box the size of a large disposable cigarette lighter that projects a full-size QWERTY keyboard onto a flat surface. It uses Bluetooth technology to communicate wirelessly to your mobile device.
When I turned on the Bluetooth Virtual Keyboard for the first time, my heart stopped for about five seconds. It is literally one of the coolest gadgets I've played with in a long time. It's from the future. But is it functional? Will you be purchasing them in bulk for your staff? For now I want to focus more on how cool this thing is.

I waved my arms in the air maniacally like David Copperfield did before walking through the Great Wall of China, and I powered the device on. People actually did gasp! Also I was escorted out of the Starbucks.
In all seriousness, this device really does make people gasp. But lots of gadgets make people gasp and ultimately fall off the face of the earth. So what makes a gadget sticky? For a gadget to stick it has to simply make sense. A BlackBerry was geeky and weird, but in the end it just made sense, and now it's mainstream. Having a laptop used to make you geeky. But in the end a laptop just made sense, and now it's mainstream. The Bluetooth Virtual Keyboard is geeky and futuristic, but does it just make sense?
How it works
First, there is software you need to install on your device that lets you configure aspects of the keyboard, and it also helps your device understand that this thing you're about to pair with is in fact an
