Well, if I understand well, this is about SVG handling in Illustrator and HTML5+CSS3 in Dreamweaver. It's indeed some sign of interest towards those technologies on Adobe's side (thought it was planned for CS6), but if I'm not misunderstood this is not nearly close to a powerful and easy-to-use, Flash-like, IDE for those new standard web technologies.

Where did you get this from?

Don't remember, but DuckDuck quickly gave me some links...

Some Adobe guys (could an independent tester check these results please ?) ran the latter test on a Froyo/Nexus1 combination, and it looks like the difference in performance is quite noticeable.

Did you realise that most modern javascript engines in browser are actually compilers? I have been told that the jargon for this is "method JIT".

Examples are Google's V8, Apple's nitro, the new Jaegermonkey engine in Firefox, and even the new engine in the IE9 beta, which AFAIK is called Chakra.
"Introducing “Chakra”, the new JavaScript engine
Script engine performance is just one part of the overall browser performance picture. Script performance in Internet Explorer 8 improved exponentially over that of Internet Explorer 7, and “Chakra”, the new JavaScript engine in Internet Explorer 9 Beta, does it again. The Chakra engine interprets, compiles, and executes code in parallel and takes advantage of multiple CPU cores, when available. For more details, see the IE Team Blog."

As for the "start-up penalty" ... perhaps you haven't considered the implications of provisions such as Firefox's new "App Tabs" feature:
"There’s a new feature coming to Firefox 4 that creates a new kind of browser tab known as an “App Tab”. The idea behind App Tabs is that some web sites are more like applications than web pages, such as Google Docs, webmail, Twitter, and web-based feed readers. These are sites that people often keep open all the time, and App Tabs makes that easier and more efficient to do."

For these "App Tabs", the underlying code will only ever have to be downloaded and re-compiled when it changes.

Indeed, forgot that browsers discovered the existence of JIT some months ago, thanks for pointing this out.
