Mac OS X and Phone market share for Internet usage dipped from January to February, according to the latest market share survey from NetMarketShare (http://www.netmarketshare.com). However, the iPhone saw a slight increase.

According to the report, among operating systems, Mac OS X had 5.02% of the global market share in February, compared to 5.16% in January (that's global market share; in the US it's almost 10 percent). Windows remains dominant with 92.12% as of February. That's up from 92.00% in January. Apple's highest percentage was 5.27% in October 2009.

The iPhone's market share also rose, according to Net Applications. The Apple device had 0.50% of the global market share in February, compared to 0.48% in January. Of course, I've long argued that the iPhone should also be included in the Mac OS X market share, as it runs a derivative of Mac OS X. If it were measured this way, the Mac/iPhone OS would have 5.52% in February.

When it comes to browsers, Safari had 4.45% in February, while Internet Explorer had 621.58% Firefox had 24.33% and Chrome had 5.61%. That compares to, respectively, January percentages of 62.12%, 24.43% and 5.22%, for the browsers.

NetMarketShares' monthly surveys don't measure market share in terms of computer systems sold. Instead they sample data from visitors to some 40,000 web sites operated by their clients.
