Here's a link to a techCrunch article that links to yet another cute little video that someone put up on YouTube. The gist is that designers and programmers hate the stupid quirks and security holes that are present in IE6 and have mounted a vigorous campaign to get corporate IT departments to finally get on with the upgrade.
But, I actually work a bit in corporate IT, at a call center full of computers running IE6. They're running that way by necessity, because many of the computers in that place are so old that they won't run an OS newer than Windows 2000. How about that techCrunch?
