Brazil provides huge tax breaks for products *assembled* in the country with local workforce, even if all the components are manufactred elsewhere. So the big manufacturers just import the component kits from China and assemble them here. This is true for Sony notebooks, the Xbox360 (recently started to be assembled here, and will start selling cheaper than the Wii for that alone), and the same goes for electronics such as phones, monitors, TVs, etc. Foxconn isn't starting up a facility out of nothing, the Sony vaio line is already assembled by them in Brazil.
Recently the legislation was changed to include tablets in the tax break law, and local assembly of ipads here will start soon. That is not a rumor and has been on the brazilian news for months, with official word from both the government and Foxconn. How much of the global market will be "served" from the brazilian output is the actual question. I wouldn't be surprised if the entire iPad 2 assembly transitioned to Brazil while the chinese sweatshops move to the iPad 3. With local economic treaties, it will be no surprise if the brazilian output of tablets starts serving the entire South America market right away.
Regarding the Argentinian coward's opinion on the quality of brazilian goods, there is no such perception of bad quality in the internal market, save for the automotive sector -- where the national industry is heavily protected and gets away with exorbitant profit margins on cars with considerably less features than cars from european and asian competitors.
