[Nirvana 2] Random Observations after pressing Ctrl+U

So I pressed Ctrl+U on the new nirvana today, here's some random thoughts:

• The HTML5 tag at the top was surprising (but exciting)
• I learned something new from the X-UA-Compatible, it chokes up the validator but it could definitely save one of my projects from its IE woes
• Images encoded in the CSS, very cool
• All javascripts and css directly in the file, do you notice that makes it faster? Most readings say you need to have separate servers for these types of things for concurrency.
• The opening body tag comes out weird, split over two lines and a version attribute. Why not data-version instead?
• All this javascript is really making the validator obsolete, but you're surprisingly close to valid.

Well that was fun, now time to look into the API...
