Browser support PNG transparency

Question

Is IE6 the only browser that doesn't support PNG transparency?

From: http://www.alistapart.com/articles/pngopacity/

It turns out that most of the latest versions of the major browsers fully support alpha transparency with PNG – namely, Netscape 6, Opera 6, and recently-released Mozilla 1, all on Windows; and, for the Mac, Internet Explorer 5, Netscape 6, Opera 5, Mozilla 1, OmniWeb 3.1, and ICab 1.9. Incredibly, PNG even works on Opera 6 for Linux, on WebTV, and on Sega Dreamcast.

IE5.5+/Win, bless its heart, will, in fact, display a PNG, but it doesn’t natively support alpha transparency. In IE5.5+/Win, the transparent area of your PNG will display at 100% opacity – that is, it won’t be transparent at all.

IE 5.5 and IE 6 don't correctly display a PNG image, they don't support alpha transparency. This can be fixed with this hack. I use it on all my sites and works perfectly.

Pretty sure that IE5 doesn't either.

I think it's the only commonly used browser that doesn't support PNG transparency.

Obviously other older browsers such as Netscape 3, IE5 et al also lack support for this but I'm assuming your question is about browsers in every day use.
