I thought the same as you. I arrived in a new country, paniced at the foreign keyboard, had family send me my keyboard from home ASAP. It arrived 4 weeks later. I tried to use it but my fingers had already gotten used to the foreign keyboard and it would have been more work to switch back. So, I was wrong. I did get used to it. I got so used to it that when I moved back to my home countries I kept using the foreign keyboard for ~2 years. Until I got a laptop with a local keyboard. At which point I finally switched back on my desktops.
