Chrome really struck a chord with their tabs-on-top approach, with both Firefox and IE mimicking it to a degree.
It's also about time IE got their shit together as a browser, both on the rendering and GUI fronts.
Ive never gotten the point why they dont really treat it as a part of a system and make sure it is absolutely right. I mean, it does come with every single windows computer/laptop.
first they need to make it standards compliant, i should not have to special mark my css/html code for IE, at least all the other browsers are mostly standard compliant.
