Take this one with a grain of salt: A video purportedly showing Internet Explorer 9 beta has found its way to YouTube. It seems rather convincing – you see the browser score 95/100 in ACID3 and go through the paces of some of the new browser benchmarks.
The biggest letdown here is that the UI seems incredibly ... mundane. I mean, for some reason the guy filming the video opened every link in a new window, so you don't get to see the tabs (which are supposedly right next to the address bar, according to previous mock-ups and rumors).
Still, for what it's worth, this leak seems to be substantial. I can only hope that something more exciting happens with the UI by the time the browser officially launches, which is pretty soon now.
