Yes, most do, else there wouldn't be so much variation built around arch and comfort, including but not limited to mice that are held at an angle or sideways (like a soda can) to improve ergonomics.To everyone complaining about the ergonomics - do you actually rest your palm on the Logitech? I have an MX3 and the only parts of my hand that touch the mouse are my fingers and thumb … exactly the same as with the Magic Mouse. If I rest my whole palm on the MX3, my fingers hang way off the edge - and my hands aren’t that big. Either people have way smaller hands than me or y’all just love to complain.
I have seen people with bigger hands prefer smaller travel mice though, but only because they hold their mouse completely differently than others. Regardless, ergonomics are a thing, even if you use a trackball mouse.
As for the Magic Mouse, I hate it. Have only used it a handful of times (heh) and would honestly prefer their trackpad over it. Never believed in Apple fans' fascination of the trackpad until I got my MBP.
