I actually find Portuguese QWERTY better for programming. It's got all the braces in 'the right places' (that is, in the same place you'd find them in an US/UK keyboard), and it doesn't have the 'ñ' character that is completely useless in anything but Spanish.

(note: I grew up in Argentina, so I'm used to Argentinian keyboards, maybe Spanish keyboards use a different distribution?)

I found as well the Spanish QWERTY to be the best designed keyboard if you type in English, French and Spanish.

The French AZERTY is so poor, it is strange it is still the default keyboard for French speaking regions.
