It's not a contrived example, as someone already pointed out.
"Nothing Microsoft does now can make up how awful IE 6,7, and 8 are and the fact that most of my day-to-day pain is caused by supporting their crap-tastic browsers. Even IE 8 leaks memory like a sieve."
This is entirely irrelevant.
Why is this comment being upvoted?
Wonder what the result would be if the video maker had tried using the WebGL extension... if this FishIE thing supports it.
Anybody can make a nice demo, it is getting people to use it that matters.
From where I sit, IE9 looks like a genuine attempt by MSFT to get back in the race.
They could add in IE7's and IE8's rendering engines into IE9 as compatibility modes, push out IE9 as a forced or automatic update and have HTML5 ready to use in a few weeks. But they seem to be more worried potential whining from update-averse users than holding back the technological progress of the entire internet.
Decisions, decisions.
(Let me hum a few bars: you use a $3 million CRM which only supports IE6, and the company which bought the company which made it has since folded. This is hypothetical, but not very hypothetical, if you catch my drift. A forced free upgrade to IE9 would create an organization-wide emergency for that customer, instantly, and it would be a cold day in Hell before they every do business with Microsoft again.)
I didn't mention IE6 backwards compatibility, because no one running IE6 is going to upgrade directly to IE9; they don't run on the same OS. Even if IE9 was made a mandatory or automatic upgrade, people relying on IE6 wouldn't have to worry. IE6 would have to be dealt with differently than IE7&8, which is fine, it'll get to insignificant market share soon enough on its own.
You can make it entirely realistic by saying the company that made the CRM now has a version that supports Firefox and IE7-8 but it costs $5M to upgrade the license. I've had so many of those cases at my current job.
My understanding is that IE's entire user-base consists of update-averse users these days - everybody who can stomach the idea of changing browsers is already using Chrome or Firefox.

I wish Chrome would take more from IE than it is from FF, but it is good to see IE6 drop so much. It's under 5% now.
Note: these are US numbers. If I recall correctly, the global numbers are shaded a little more non-IE.
Edit, security ok, version upgrade not ok.
So if MS did what you ask tomorrow, nothing would change in 99% of big corporations.
