Here's the issue with these kinds of studies: They take examples of building apps using build 0 of a toolkit or technology, then by the time the study comes out, that same toolkit or technology is on build 100.
The usability of web apps (specifically speed) is improving faster than we can develop our non-trivial apps for this platform. In short: time your version 1.0 with the assumed capability of the host platform at the time of release, plus two years. If you commit to spend a year on AIR development, because ajax or js execution or whatever is not where it should be right now, you're making a mistake.
That's what's bad about pre-obsolescent technologies like AIR - they distract from the future in favor of right now.
