Excellent, and often overlooked point here - "We made the visual design look a lot better in Internet Explorer."

If you look @ general consumer market a huge share are still on IE. What's more striking for some of our clients is that an even huger share of BUYERS are on IE.

EG - maybe 40% site traffic is IE, but 55% of their buyers are IE.

Lesson is don't build in the what-you-use echo chamber - analyze your customer profile as it emerges and build for them.
