Dan and I have been going around on this for awhile now privately.
Frankly, I'm not a real big AJAX fan. In fact, I think it's not much
more than the current flavor of the month.
A couple more bullet points to add to your list:
1) How many companies would seriously consider using AJAX (or Rev for
that matter) for a large-scale revenue producing project? Not startups,
mind you, but companies who really need apps that perform...like Adobe.
2) And this one really gets me. It's bad enough to have to modify your
code every operating system update, but with AJAX and LASLO, you now
have to provide maintenance on every browser version update (Firefox,
IE, Safari, Konqueror, Opera, PDA browsers(?)) as well as every Flash
plugin update. Not to mention you're at the total mercy of the creators
of those products as well as all the standards committees who are
'pushing for nextgen' type stuff. So, if Macromedia thinks Flash is too
difficult to program and change their scripting paradigm for Flash
(they've done it 3 times before!)-- your hosed. Or, MS decides to no
longer play nice with CSS standards groups because they don't want to
lose any more market share (heck they do this already with the .doc
format) and purposefully make their browser incompatible-- again you're
3) Ever try debugging AJAX apps? Whew!!! From what I know, there are
in browsers these days.
Just a few of the many reasons I don't really see the 'browser based
apps' ever really competing.
