]When the market leader has 80% and you have 10%, you're obscure whether you're Apple, Microsoft, Dell, Sony, Motorola or anyone else. That's just the truth of it.
when you have 10% of the hardware market, a very large chunk of the portable media player and smart phone markets you're not a little player and you're not obscure not matter what some-one might think.
Separate the company from its products.
Using your reasoning, Nokia is a significant player in the handheld games market with the N-Gage because they have a huge handset marketshare and are hugely popular in Europe. Microsoft is huge in the portable media player market with the Zune because they have the world's most popular OS.
No matter how you slice it, Nokia and Microsoft are obscure players in those two respective markets the very same way Apple is in the computer OS one.
