I've tried wireless and for me it didn't stick.

I never need my keyboard more than 1m away from my monitor anyway, so the upside is limited.

And I had a succession of mysterious, intermittent, difficult to diagnose problems. OK, so I think I'm getting lag and dropped keystrokes. Is it RF interference on a crowded 2.4GHz band? Is plugging the dongle into the back of my PC's metal case just too challenging? Are the batteries low? Is everything fine, and I was just miskeying my password? Oh, for some reason the problem's gone away... for a few hours.

Switching back to my wired keyboard made the problems disappear.
