Doesn't Netflix use Silverlight? Might explain the high figure. Also, the browser stats might just be based on the default browser rather than what's installed, otherwise it'd be a pretty pointless figure.
As for graphics card sales, Vlad, I think the usual figure is around 80 million per annum. Obviously they're not all going to be top of the line cards, but there again they're not going to be sold to business users either.
