Well there are certainly people who no longer support ie6  e.g. google 
facebook and so on, IE doesn't support it unless you run vista or later. 
and it will work on xp if you use firefox.

we use it with api's and non-browser-based html5 applications with 
essentially no issues.

The market-share of some of the more problematic devices is in fact 
getting to the point where it is possible.
