Over the last 7 or 8 years, I've had the opportunity to speak to quite a few audiences all across the globe. A major component of many of those audiences has been college students and so I'm not at all surprised to read of this Eduventures study which says that among college students, the divide between those who prefer IE and those who prefer Firefox has narrowed to zero.
The study finds that 45% of college students prefer IE, 45% prefer Firefox, 5% prefer Safari, and lesser known alternative browsers make up the remainder.
