From Silicon Alley Insider, June 24, 2008:

Why is Nokia (NOK) spending $410 million to buy the rest of Symbian, the smartphone operating system it co-owned with Sony Ericsson and others? Because its continued dominance of the smartphone market -- 60% of the install base, according to its press release -- is anything but guaranteed.

Buying Symbian won't help Nokia build sexier-looking, high-end gadgets. But in theory, Nokia's ownership will speed up Symbian's platform development and could allow Nokia -- its biggest customer -- to come out with more phones, faster.

That's important as new competitors enter the market with sexier, more exciting products, like Apple's (AAPL) iPhone, which is just opening up to outside developers.

So far, Apple's success has mostly been in the U.S. But this year, it will start selling its iPhone in more than 70 countries, at a lower, subsidized price.
