I have a fairly severe neuropathy which limits how I can move my fingers. I have spent years trying to find an input device that works for me, and allows me to be nearly as productive as my less disabled colleagues. The nearest I've come to it is the Kensington Expert.
However, I still find that my hand will fatigue and ache, and it is helpful to be able to switch hands. I want to be able to do this dynamically and quite sporadically. Obviously I can plug two Experts in, and switch between them, but I need the controls on each to be a mirror of the other. Is there any way of doing this?
The alternative will just be to get an L-Trac and by virtue of the fact they use different drivers they could be configured differently. However, the L-Trac is hard to get hold of at the moment, it's much more expensive than I can really afford, and given the limitations of my fingers, I don't think the scroll wheel placement will work as well for me as the scroll ring on the expert.
Any suggestions would be really helpful, oh and I'm using Windows, but it'd be good to have something for Mac OS too, as in my industry some offices use Macs.
