In the 1800's, different railroad companies around the world used different gauges for the rails, making trans-national travel very difficult.  Because of companies like Apple, the same thing is happening in the mobile development space, according to Adobe CTO Kevin Lynch.  Lynch responded to Apple-propagated misconceptions about Flash and HTML5 at the Web 2.0 Expo.  "It’s not about HTML 5 vs Flash.  They’re mutually beneficial," he said.  "We’re going to make the best tools in the world for HTML 5."

IE9 Delivers Second Preview as Promised
Microsoft released another preview of IE9 - this time with a new ACID 3 score of 68 out of 100.  Microsoft says that they've gotten a 117 millisecond speed improvement, according to the SunSpider benchmark.  The company has now submitted a total of 183 standards compliance tests to the W3C.  In this release developers can now experiment with sending different user agent strings to sites with every request.  One Microsoft evangelist said that he wanted IE9 to include the HTML5 Canvas tag, but it won't.
