I also can't use any other device but the simplest, most standard, compact and light plastic mouse. my current one doesn't even have a brand on it. I handle it with the tips of my fingers with minimum effort. Years ago I suffered a lot of wrist and finger pains from mice I had to fight with for long hours, I moved from it to Wacom tablet and pen for several years (as a total replacement for a mouse, not just for creative work), it also operates with no efforts so never caused me pain and fatigue, even though the pen buttons were always a bit tricky to operate. I used to set the tablet's "active area" to about 9x7cm (something at the size of a track pad or even smaller) which enabled very quick and easy cover of the screen with reasonable accuracy. It may have been that I lost the tablet's pen or gave it to someone one day, I'm with the most humble mouse out there since.
I hope it's ok (remove if not) to ride on this topic, asking the same question about this g' I came up with while working on a new typeface (and another one). It is an hybridisation of two and one stories g'. Do you know any? What do you think about it?
