I also switched to a US layout from German layout. It took me a while to get used to typing Umlauts (on a Mac, you type option-u followed by a/o/u to get ä/ü/ö), but after a few months it became very natural. My home computer is in the living room shared with my family, it still has a German layout, so I switch between US and German pretty often. I can type on both keyboards fluently. Somehow my brain knows that the computers have different keyboard layouts. The only thing that still confuses me is a cheap backup keyboard that I have (when bluetooth doesn't work), which has a UK layout....
