For dev work an US keyboard is actually preferable.
While we’re here, let me just add another little form of “geographic advantage” (?) to the mix: you all know cmd-‘ pages through windows of the same application. On a US layout ‘ is right up next to tab, which makes it extremely convenient to remember the mnemonics of cmd-‘ and cmd-tab. In US intl ‘ is shoved down next to lshift, and the premium key top of tab is the useless §.
It is ridiculous how hard it is to get ANSI keyboards here (Germany). Laptops are ok (Macs, Lenovo and Dell) but external keyboards (especially mechanical ) and any other laptop brand are a huge hassle.
