Yes.

No.

I'm also used to pt-br keyboards, it's easier to type in my native language, but it's ok if I need to use US keyboards. In terms of muscle memory, keyboards are far harder to adapt.

A non-tech example: if I go to a Japanese restaurant, I'll use chopsticks and I'm ok with them. At home, I use forks and knives because they make my life easier. I won't force myself to use chopsticks everyday only for being prepared for Japanese restaurants.
