That's how you start in a market already dominated by competitors.
Just as a comparison, only Apple managed to sustain ~5% market share on the PC market since MS has dominated it. Entering the mobile market is very similar in difficulty to entering the desktop segment with a new OS.
The problem is that Apple still has a single digit or low double digit percentage of the PC market. And the only reason they can make it work developing their own ecosystem at that level of market penetration is by being a premium brand with high margins. Nokia's market share is currently at the opposite end of the market. Which is bad news for attracting developers, because developers won't want to target a small minority platform full of budget-conscious customers.
I Brazil, at least, Nokias are being heavily subsidized. Not only to the carriers, but salespeople are getting commissions straight from Nokia in order to push as many as they can.
In Brazil taxes do not "penalize" countries, products or companies.
Right in the middle of the Amazon region there is a development zone where the majority of the electronics are made, in the country, by multinationals. It is called a Zona Franca.
When built in the country the import taxes, which represent the majority of the cost for imports such as electronics, these taxes are removed and make the good much cheaper.
It is the same with Xbox and PS4 in Brazil. An Xbox is 4 times cheaper than a PS4. If Brazil would be against USA or it's companies then it would be the reverse.
Hope I helped.
ps. Many people in country complain about the taxes but forget that when companies move their industries to Brazil, jobs, money and know-how stay there too improving the competitiveness. Sadly the vast majority of the population will look the price tag and complain without knowing the implications behind.
Tariffs definitely do penalize foreign countries/products/companies. Not to say they're a bad idea for Brazil and other emerging countries with large markets, but if everyone had such harsh tariffs, free trade and progress in general would suffer.
Not everybody could do it.. only countries with big markets could have this privilege..
Small contries would get simply ignored by the industries, since its too much trouble..
So it would get reduced to: China, Russia, Brazil, US, Japan.. and if managed in block: Europa..
This policy from Brazil is not a bad one if you think that the only other possibility left for industrial growth(technology transfer) would be one of the cheap labor.. like what happened in China, South Korea and the Asian Tigers..
