My setup at home is a 3-foot monitor that I sometimes split-screen Mac and Windows on. I don't like to use Mac keyboards on Windows (and vice-versa), so rather than using Synergy I have two keyboards / mice at the desk -- one on a tray, and one on top.

It works nicely for me.

In my experience I've yet to encounter a USB switch that will forward the LCD display data properly to the G15 keyboard. Although, I was using cheap USB and KVMs switches.

Another good question is who uses an overpriced "gamer" keyboard for work?

"Gamer" equipment tends to be far more reasonably priced than most good office-oriented equivalents. They also seem to be the only laptop segment that hasn't completely fallen to anorexia.

My old company ended up standardizing on Fnatic keyboards because they were the cheapest way to get silent Cherry switches with a reasonable layout.

I also used a gaming MSI laptop, because it was cheaper to buy and upgrade that than to buy a reasonable business Dell. ThinkPads weren't much better eiter (but also not an option anyway, thanks to Superfish and co).

My office has a large number of what I'd call "gaming borderline" keyboards mostly because people are looking for whatever has decent switches for not high prices. Also why Logitech makes the K840 I think, not that I'm recommending it.

Gaming keyboards tend to be the cheapest high-quality mechanical keyboards.

This looks like something out of the Terry Gilliam movie "Brazil".

on TV shows, when someone has that many keyboards then their desk is usually also inside a Faraday cage.

Someone who hasn't heard of USB Switches.

Last time I tried a usb switch it would flip out and cause issues (it was doing the monitors too, and it was cheap). I forget what the specific use case was, but at my house we definitely had 2 keyboards on top of each other. It was a temporary set up of two computers at the same station, so didn't warrant looking into a better switch. If I ran that setup daily in the long run, I probably would have.

Someone who's IT department has plenty of keyboards but no USB switches on hand at the particular minute they are given hardware.

I've seen people have multiple keyboards for creative suites (editing).
