Certainly seems as though it qualifies as a "gee-whiz" keyboard!
If it worked perfectly, didn't cost too much, and never ever caused, or might cause, any problems with Windows, or any other program, it might be worth considering.
I'm usually extremely conservative when it comes to attaching anything new or different to my computer, because having hardware, Windows and programs work perfectly together can be an issue, and I have to prove to myself that the perceived benefit would outweigh all the problems that might occur!
