well i found some stats from oreilley folks. unfortunately they give nothing about the sample size, hypothesis test parameters, etc... but im not gonna lose sleep over this any more! maybe some eye-care insurance company bean counter might care about some implied claim, but i sure as h* don't (h* => whore derves)!

======================
I was surprised by the number of users who choose non-default text size settings in their browser. Although this may be due to a selection effect (this data comes mainly from Museum websites, which may have a particular audience), the figures are still surprising:
Font Size (IE) % of users
Largest 4.1%
Larger 2.7%
Medium 88.9%
Smaller 3.1%
Smallest 0.9%
(give or take rounding errors)
