Can you Track Browser Share?

I was wondering if there's a way to analyze how many leads use a certain browser?

For example, run a report that displays market share for 1000 leads:

Internet Explorer 7: 10% (100 leads)
Internet Explorer 8: 20% (200 leads)
Internet Explorer 9: 30% (300 leads)
Mozilla Firefox 23.0.1: 40% (400 leads)

Something like that?

Thanks!
