Surface: The coating of the plastic shell? Any suggestions perhaps? Or the rubberized sides and the patern also?
Surface/coating: yes, the coating everywhere - buttons and shell. I cannot stress this enough, for example: if I place my fingers on the X I, I can almost lift the mouse off the table without exerting any force, just by the friction of my skin and the plastic shell. With the Xornet II I have to consciously grip it and apply quite a bit of force with my fingers. This essentially makes the mouse feel 4 to 6 times as heavier to me. The side grips get worse once my skin becomes more humid, as opposed to the shell which presents only a slight improvement. One thing that I just can't understand about the side grips, is why you have chosen to use a pattern that essentially amplifies sliding, acting as a guiding surface for your thumb to reach the -see below
The side buttons: the side buttons are bad for me in the sense that below them you have placed a sharp edge (the english term is eluding me right now) which is distracting / discomforting. The whole thumb rest area could use an entirely different profile in my opinion.
The Xornet I had some intrinsic problems in itself (forcing too much pronation of the arm, other finger distribution profile issues etc), but the X2 just exacerbated everything to the point that I am looking at different mice now.
I'm not bashing, or pretentious, it's just that I've been a junior product designer once and I tend to observe these things. With so many bad input devices on the market - my daily driver right now is a 8 Euro mouse from a very circulated brand. I am utterly surprised at how many things they managed to get right with it, and just as saddened to know that the design will never get to see a selection of quality components.
Many thanks for being interested.
