ggibson1 rho Market share? "most people do not bother switching browsers"? Here are actual usage statistics: http://www.w3schools.com/browsers/browsers_stats.asp
Your "actual stats" are showing a self biased population of people who choose to visit that site.
I see a lot more raw data than w3schools does and I was surprised to see more people use Hotmail than Gmail and IE is still the most used browser... but then again I work in IT and the small number of people that I work with is not an indication of the over all population... the data doesn't lie, but the person picking the data can >-) ... kind of like the saying that he who counts the votes chooses the winner...
So for gaming if you want to have support for things like game pads it is probably better to ship as a node web kit that has Chrome built in if you want to make sure all the users have that functionality.
