This list should be a lot longer than 6.

Sites you would like to load test or functional test with standard tools.

Sites you would like the vision-impaired to use.

Sites you would like to have a fully functional back button.

Sites you would like to open source, as the tools to write flash cost significant $.

Sites users might like to copy and paste from.

Sites where users might not have flash installed for security or other reasons.

Most websites not involving video or games.

Note: if the flash is just a "garnish" some of the above do not apply.

A list of the few places where Flash does belong would likely be more effective and exhaustive.

This was a great article, from someone who clearly cares about usability and customer satisfaction. Although many of his points are arguable, it really comes down to one thing: choosing the platform.

Choosing a platform always has trade-offs, and the flash vs. html is no exception. When you decide on a platform for your application, it almost always means your going to exclude users from accessing it. I.E Windows software is generally not usable in OSX or Linux, and Mozilla extensions are not available from other web browsers.

Another thing - people develop levels of comfort with platforms, and switching can be a daunting experience. It's hard for the average Windows user to switch to Linux, because so many basic features of Windows are missing, and the user experience is so different. Same with flash vs. html - things like ctl+f don't work, text highlighting is different, the presentation is not as familiar.

Any smart person will consider these platform trade-offs when developing an application. You might lose some users, but I think people appreciate high-quality applications with good UIs. I don't mind waiting a few seconds to see a beautiful flash site to load (www.schematic.com, for instance).

Let's add 'a public website' to the list. The Flash runtime is proprietary and simply isn't available for many environments.

Opera on the Wii ships with Flash 8, but many new Flash video players use Flash 9. There is also no decent Flash build for many unix varieties, including 64-bit linux. (Yes you can install 32-bit libraries to get the 32-bit version running, but come on ..)

The "E-commerce" entry left me flabbergasted.

Do some developers really think that people want to drag-and-drop stuff into their shopping carts?

Maybe I am too used to sensible on-line shops...

In any case, that can easily be done in JS.
