I have been a member of this community for the sole purpose of discovering a decent mechanical keyboard with wireless connectivity. I haven't been using corded HID devices for ~8 years now, and while I am willing to pay double for mechanical novelty (to me at least), I cannot afford the inconvenience of a cord.
I get some people prefer having constant minor inconvenience of the leash over the occasional major inconveniences of connectivity issues. I just don't. All the other people with wireless keyboards, mech or non-mech, also don't.
