On the Web, IE filters are more widely used than SVG filters, yes. It's 
not used as much as most other IE extensions, though.

Some of the more commonly used filters are the one you mentioned for PNG 
transparency,and also those for flipping and rotating content. Most uses 
aren't very obvious, you just tend to find them deep in stylesheets (e.g. 
to rotate text in a table cell so that it goes vertically).
