The factors that led them to choose IE..
News.com.com.com is reporting that Firefox is gaining on IE faster than expected. Amsterdam based OneStat.com has IE's market share as low as 88.9%. I can't help but wonder if those guys didn't hit the hookah a few too many times before running the numbers. The Mozilla Organization has been saying that they hope to have 10% of the market by the end of 2005. You could project that they might reach that by the end of 2004 if these OneNet stats are accurate, which they most probably are not.
Sigh
At any rate, check out this gem from Microsoft's director of product management for Windows, Gary Schare (pronounced Gair-ee Share-ee ;)
"I still believe in the end that most users will decide that IE is the best choice when they take into account all the factors that led them to choose IE in the first place," Schare said. "Meanwhile, we're happy that they're primarily (using Firefox) on Windows, and that Firefox is part of the large ecosystem of software products available on the Windows platform."
The "factors" he references are covered briefly here, while more on the "Windows ecosystem" he mentions can be found here.
