Not any more. Yesterday Microsoft published their fourth platform preview of Internet Explorer 9 – the last browser to get native SVG support – and I am here to tell you that it renders a lot of SVG content as was intended, right out of the box, the only caveat being: your box must be at least Windows Vista.
Check it out for yourself e.g. with this Price Kaleidoscope you might have seen at some conferences.
If you’re stuck with WindowsXP in your office and wonder when this ubiquitous SVG world will come to a desk near you, you might be interested in SVG in Internet Explorer, a paper about possible transition strategies.
