Well, to begin with, I like that it’s wireless, and there’s no wireless PS/2.
Also… I like this specific mouse, and it doesn’t come in PS/2 form. It might be possible to make a PS/2 version of it, if you ignore the wireless part, but nobody’s going to.
Mice aren’t fungible: This mouse has a good feel in the hand, a long battery life (with a well-designed battery case), the right number of buttons positioned in the right locations (including a pair of side buttons I can use to go backwards and forwards in my browser), a good clickable wheel which has a fast free-wheeling mode, and a non-annoying blue laser which works on all reasonable surfaces.
I used mice back when mice had balls. I remember the old red laser mice which really required a mousepad, and mice without scroll wheels, and mice with only two buttons so you had to press both at the same time to middle-click. Going back to a PS/2 mouse would mean going back to one of those kinds of mice, from all I’ve seen, and that would be a step down for me.
Okay, so those are almost entirely all subjective issues, which apply equally to my longstanding choice of (wired) (USB with PS/2 converter) trackball. I wouldn’t argue any aspect of the need for an exact personalized fit.
I don’t use wireless HIDs myself, if at all possible. Just one more layer to fup uck, which it seems to do with regularity, and after losing 15 minutes of every third weekday trying to get a (expensive, high-end, brand-name) wireless set to connect in the morning it was a last straw. There’s next to no justification for wireless keyboards and I find the difference between wired and wireless mice to be somewhere between trivial and theoretical.
As a mouse man — I don’t even care for keyboards let alone touch — I rely almost exclusively on an old school Cherry M-5400, wired, laser, 3 buttons, wheel, 800 dpi, neither too big nor too small. Nothing is better than a Cherry.
I’m under the impression that mice can have more buttons and higher precision (aka resolution) on USB than they can on PS/2.
I also definitely found that hotplugging could be a problem, and not because of things burning out. Just that often I would have to restart the computer to get the computer to recognize the keyboard or mouse being plugged in. It wasn’t consistent, except in one case: if I booted the computer without a device plugged into the port, then I could not plug in a new device and have it work without rebooting.
Other than that, I presume it depended on what was going on when I unplugged it.
