HERVé 5  I'm surprised many comments seem to consider Amaya as just a browser, when it is a complete, non-proprietary, WYWIWYG html editor.

Recently I had to prepare a quick how-to for a small community server and I wanted something else than iWeb: I dare say Amaya did it without even opening a single help file.

I preseume it can do much more, but if what you want is an html editor that just behaves like a text editor (with links etc.), give it a try !

GAOSHAN  In its day Amaya had a useful purpose. Anymore, however, it seems extraneous.

BUMBLEB  JAVA as it is implemented here, simple does not cut it on Mac OS X - we are too accustomed to Cocoa goodness;-)

ORION MK. V  Ugly, clunky and nonintuitive, so despite any novel/unique features it's just not particularly usable.

ANONYMOUS  Amaya may not look as good as some other browsers, but it's the only browser to really do things with link, Xpath... It's the playground for new W3C technologies.

AMAKE  It's nice that the W3C decided to put Amaya out for OS X, but it has a long way to go before it becomes a decent browser. Gecko and KHTML are light years ahead of it in terms of rendering accuracy, and Amaya can't even display non-English scripts correctly (I specifically tested only Japanese). At this point it seems more like a curiosity than a fully functional browser, though perhaps its editing capabilities are more worthwhile.
