I've been looking for something for quite some time to come out of the input device market that would allow me the functionality of a mouse while allowing me to comfortably remove my wrist from my desk. It can't be healthy to have the pressure on my carpals for 4-8 hour periods of time and, if anything, switching to the side of my hand would be a welcome change. I will be waiting for the reviews on this.
And constantly using a pen for hours produces no strain injury at all.
Have these people even attended school? At all?
I clearly remember how my hand and fingers used to hurt from writing a lot of stuff. Some of my... hard-working classmates even developed severe injuries: their middle finger was deformed from holding the pen for so long.
i have a bamboo pen/touch which is a similar size around the girth of the pen. after about 30 mins of using the pen i start getting cramp in my fingers. even after over a year i still get cramp. so to me this is just another gimmic untill they can get the overall size down to something that is as thick as a biro.
