Query: Made co-workers envious...

I paired mine with my UMPC(a tablet PC), and I'm pretty happy with its performance. The fact it's bluetooth is great, I don't have to cable it to the UMPC.However I wish that Celluon had a version with a "traditional" PC keyboard layout. The first thing you notice with PC/Laptop/UMPC use is that the function (F1 - F12) are missing but are replaced with shortcut keys to things like email, browser, calculator, etc. I suppose that I'll get used to it.The accuracy is actually better than I had expected. But you have to remember not to "hover" your fingers over the keyboard. The sensor will see your fingers at around 1/4 inch above the surface.It's also been bright enough to see in well-lit offices and in restaurants (not direct sunlight though). Another plus here is that the keyboard has a brightness control.So if you need a keyboard entry device for your electronic goody, consider the Celluon.
