Doesn't Dell, HP, and a number of others have manufacturing in Brazil under better tax regimes for the parts? I remember one of the points of the Zona Franca de Manaus was that - build a factory and enjoy tax breaks mostly for your imports.
Apart from that, this is something that affects the HN crowd and almost nobody else.
For some definition of "manufacturing". More like final assembly. Brazil hasn't attempted to create its own computer technology since the military dictatorship. For example, there are no brazilian semiconductor fabs that would be even remotely competitive with the current state of the art.
