I thought I'd share my findings:
the hardware is very well done and works great.
The software is far from completed and lacks basic features: can you believe it isn't possible to assign the mouse mode to the g940?
the nice ministick pov in mouse-mode could have been brillant
Also the deadzone of the toe tips break start from the middle of the axis, and not from the side so it isn't possible to limit the toetip deadzone/sensibility at the moment

Does anybody know the email address of somebody at logitech I could buzz with these?
THis are easy to implement features and I really wish they'll make it in the next software release
THanks
