That Joystick is kinda interesting, i want to see a review of it in action.

I am not into very lightweight mice, but 127 grams is very heavy and painful for the hand. Something below 100 grams would be perfect.

As much as I complain that Asus has been charging a bit too much for their products, I gotta give credit for them for trying out new stuff. The replaceable mouse switches are something I wish more mice manufacturers would do especially nowadays where people now know that there are mouse switches other than omron 20m and are more eager to try out new switches. This would help people try out Kailh GMs and Huano switches to better suit their preference w/o going thru the hassle of de-soldering their old switches. Much like how Mechanical keyboards have now ventured into hot swap sockets

Needs a lefty version. Using the digital joystick for a dial menu with semi transparent on screen macro's would be really nice especially if you could customize the menu's a bit in terms of where they are displayed and overall how they look. Basically hold a button select on the digital joystick dial let go of button execute the macro. That would be great 8 tidy macro's that are quick and easy to access and with a on screen visual overlay you can place wherever. Then with a left/right hand version you can double down on the amount of button macro's plus improve mouse movement further using two mice together to improve speed and fluidity of mouse input movement.
