I wouldn't mind if Dart didn't support older versions of Chrome or Firefox because that's just much different than IE 8. Most people who are running IE 8 are random non-technical folks who are using the browser that came with their OS. They don't even know what "internet explorer" is. There are probably a small sub-set of people who have Firefox 3.x because their brother's uncle's nephew installed it once like 5 years ago but I honestly don't mind losing these people as potential customers because it's such a ridiculously small %. I also feel like these are the type of people who would be more than capable of upgrading if they kept seeing messages like "your browser is old as time itself, upgrade or find someone who knows how to do it for you!" through friend/family assistance. I can't justify throwing away almost 10% (IE 8) market share for Dart and the idea of supporting multiple versions of the app is just too much work for too little return.
