I agree that this is very important. We all know the IE-only websites. I'm using Safari a lot, but sometimes i have to fall back on Firefox for the webs that don't show well in Safari. I know, i know, that's a problem of that particular website and that should be fixed, but if the maker of the website doesn't want to fix it because he doesn't care about Webkit-browser users, it's me that needs to solve the problem. And Mozilla works for me. Slow, but it works. So in reality i would prefer that they optimize the Mozilla code to be as fast and lightweight as Webkit is than to develop a third browser for the N800.
But that's just me.
