This list is so amazingly curated. Everything nobody needs and IE implements is in. Everything developers need to provide better experience and IE doesn't implement is out. The absolute best feature: "Tools that show pages in different rendering engines to let developers understand and debug browser differences" .. I wish this actually referred to Chrome Frame :-D Also peculiar: The top table doesn't align with the rest in Gecko and Webkit. Being the longest of three, I'd imagine the Firefox table header would expand it's column, not compress it. And shouldn't those tables be tbodies according to semantics?
