To put it another way, we'd still be experiencing the same reduction in income per visitor even if there was no choice of browser beyond IE.
Not necessarily more savvy, but possibly burned by the internet.
Many decide to switch browsers because they get hit by a malicious website that forces IE to download a virus or something nasty.
Firefox has better tools to address the malicious website issue so it's an obvious choice for people to use.
