The funny thing is that all of the lefties I know just adapted to the right-side mouse (likely just because that is how it was setup at school/office).
While yes, the BT mouse is going to be the better option, they're pushing the kit-included mouse.
Me too. Due to some issues with right hand I retrained myself to use mouse with my left hand. Now I can use mouse by both hands, and in both button orientations.
Switching is easier than most people imagine, IMHO. I started to feel the beginnings of an RSI and went from right to left for half a year or so, no problems.
You basically just convinced me that I should be training my left hand to use my mouse. In all cases except precision work (eg graphic design) it should be doable.
Side note, but if you actually do graphic design, get a digitizer/gtaphic pen tablet, it is simply "another world" when compared to mouse, nowadays even an el-cheapo one ( i.e. something in the 40-60 US$ range)is good enough for non-professional use.
Actually this has little to do with being left-handed, it depends on other factors.
I am right handed and use the mouse with the left, so that I have my right hand "free" to use a pen or the (right side) numeric keypad when crunching numbers.
And I do not (as many left-handers do) "invert" the miue buttons, maybe I am strange/an exception.
Then you've never seen my desk! (About 10-15% of the population is left-handed)
But really, the Pi 400 supports Bluetooth 5. So I expect many/most folks will go wireless for their rodents.
