I'm a little jealous of people who live in bilingual countries. Other than three years of low-budget high school French, I've only got English. It seems like having more than one linguistic culture in the brain might add a richness to consciousness that I'm missing out on.
I bet if you practice enough with both keyboard layouts, you brain will make room for both. Might take a while, though. Kind of like memorizing different pieces of music on the piano.
