If you were purely using it for the trackball you could get away with lots of positions, but kind of the split ergo keyboards with thumb area trackballs and then button banks a lot of the functionality comes from also being able to top-down finger track more naturally and not solely using a thumb, and with greater precision due to tracking on a single gesture or spin due to size. edit for clarity: you do finger rather than thumb tracking when going to the button bank on dual trackball ergo moving from thumb to finger tracking with thumb doing button presses + software doing trackball "layers" for hand still on keypads if desired. For the Huge it needs to be angled pretty steep if totally reversed to stay in for thumb if its facing you, and for the handshake position you're putting your finger on the large "bottom" button as your right mouse with the split opposite side of mouse wheel being two buttons, and as you noted the plug in cable support would be awkward but doable with long enough cable or an adapter that is flexible, I'm imagining in a kind of handshake position with its "natural" orientation facing the pc / forward though and a huge ass chonk of plastic blocking any natural grip. HOWEVER, the grey ball button model at least does not have full length activation for theoretical "right mouse" in that orientation even if you remapped it, so you would have a pretty unnatural "back" of button press (that is forward press when facing the right way and using thumb activation). The more expensive high dpi version on Amazon / website for "gaming" might not have the grey ball cheaper model forward only click on that button, but to me it kind of kills the idea. I had a similar thought for ease of use with the scroll wheel and how easy elecom software is for "normal" button function + additional functions. But sadly that one key doesn't have full actuation, if you're skilled enough to reorient the click you'd be able to go whole hog and use the internals on a fully custom mouse so if that's you then good luck! edit: using the right mouse button would be like using this acer mouse without the forward click part on the right basically, so the back right joint button, left joint, and better elecom scroll wheel with "middle click" and tilt. https://www.amazon.com/acer-Bluetooth-Ergonomic-Rechargeable-Programmable/dp/B0FKMSNG2B
