> There really is no reason to switch between actual physical keyboards to use a different keyboard layout, even if you need to look at the keys(and it would still require you to switch layouts in software). Surely googling a layout cheat sheet is easier than switching keyboards.

In my case, more than switching, it's that my laptop has a spanish set (work provided), and I went through the trouble of buying an external one with an English layout. It's not like I'm switching between them every few minutes, the Spanish one is left unused. I don't even bother switching layouts, since I can perfectly write Spanish with the English layout (the only missing keys are accents, which I omit in informal texts, and the ñ key that I can get long pressing the n).

I could use the Spanish one and look at a cheat sheet from time to time, but it's inconvenient enough that the 40 extra bucks feel like a good inversion.
