Myself, I do find the device useful; it just has some annoying issues, including reliability, that I believe can be improved--and no, I can't design (or at least build) a better one, but I can improve the one I have. To me, this seems no different from making an 'improvement' on a new car (new stereo, wheels, or whatever) to make
your goods more suitable to
your needs or desires. If you like it the way it is, you shouldn't change it. Follow your bliss...
