I am not unwilling, at least.
I bought it in an attempt to have an ergonomic keyboard, however even after overcoming the initial difficulties in usability (rather than binding it to my hand it works much better if I let it float around), I haven't been able to spend as much time with it as I would have liked. Consequently my hand flexibility isn't as good as it needs to be to utilize the Twiddler fully. Pinky strength isn't great either. Need more pullups.
I believe at this point I need not a good keyboard but a good mouse (tendon problems in the right hand aren't due to typing but due to the laptop trackpad combined with a lack of exercise; I twiddle left-handed). Too bad I can't buy an accelerometer mouse (I can deal with drift probably).
I may be slow to respond due to college, but we can continue this conversation via PM.
