Amaya looks very cool, first of all as a seriously compliant renderer, and secondly as a sane editing platform, allowing real WYSIWYG capabilities.
However it seems more like an industrial tool, far removed from the cheap and cheerful (ugly?) trident IE engine. And requires a decent graphics card, not something that should be in the base system.
I would suggest an ideal solution, for those that are still hooked on the IE interface, create one of those slim multi backend browsers with a simple IE like shell. So then users/distro makers can choose from engines such as gecko, webkit and amaya etc or even trident if it's available
??!
That is the advantage of IE, it's simple, reasonably effective, and just there. With this slim GUI approach, one would start up 'the internet' and it one just has to download a 'plugin' for the rendering engine (atm obviously the mozilla activeX control) and away they go. In the future, distros would probably remove this step with their prefered rendering engine.
Essentially like the curent wine approach, but so you can change the rendering backend at will.
For those that want the full personal browser experience, it's still there, but the convenience of IE is still there at minimum overhead.
