Sadly, Microsoft's Internet Explorer still maintains a strong lead. IE10 seems to be quite solid, but it will be available only for Windows 7 and 8 (and not before mid-2012).
IE8 will be around for years because XP can't get an IE9/10 upgrade. It looks like combined IE6 & IE7 are around 6.5% in North America. IE6 is around 1%. Being able to stop supporting IE6/IE7 is still huge. Yesterday I noticed that this map app no longer supports IE7.
