One of the more annoying things I've found moving country is the unavailability of keyboards / laptops with the layout I grew up with. I find it especially annoying as the country I'm from uses a US layout which I naively assumed would be easily available everywhere (and it is available but not without a long delivery and a premium price)
Side note: helping my French housemate with his uni assignments was an experience, none of the symbols were where I expected them to be
Meh, takes you like some days to get used to another layout being visible on the keys, while your OS (and brain) actually using another layout.
I've used US keyboard layout since I started programming (my first mentor essentially forced me to switch to it, he was right about it being easier), but throughout the years been using Swedish, Norwegian, British, Spanish and French physical keyboards, never cleanly mapped to the actual layout I've used on the OS, and never been an issue.
The last part though, is a real one, trying to pair program with Spanish programmers always have at least one moment of holding Shift and sliding the finger across all numbers to see where that specific symbol actually is.
