Browser wars are always fun. Not because they are definitive or slam dunk tests that once and for all decide which is the best browser, but because they induce so much chest thumping about standards, specs and specific environments for testing. It's like saying your football team is the best--sure it may or may not be true, but sometimes it's fun to throw the war paint on and act like it is.
In this case, Derek Snyder of Microsoft demonstrates once again the famous "HTML5 fish test" (see MIX 11), comparing it between a BlackBerry, Samsung Android Charge and an iPhone 4. And once again, Windows Phone Mango clearly beats everyone, coming in at an astounding 50 FPS. But what makes this test more interesting is the fact that the iPhone 4 is running the iOS5 beta 3 (just released) which puts Apple's "fall update" up against Microsoft's "fall update", making it a more realistic comparison.
Your move, Apple.
