Dear large company CIO,
It's obvious that the usage of Internet Explorer 6 is falling every month (20% as of Oct 2008).
With the rising adoption of the CSS 2.0 standard, we are seeing more sites that are incompatible with IE 6. The example below is from www.powerset.com:
Designers are just not willing to do the extra work to make their sites work with the older, incompatible browser, or they want to use the newer, CSS and Ajax friendly features available now.
This means that our users will not be able to view them correctly, rendering the web site either unusable or degraded in functionality. See related research links below.
Apple, Facebook, The Washington Post, and others all think we can put a stake through IE6.
How 'bout you?

Apple's "me.com" not compatible with IE6
As a web developer for a large corporation, I can tell you that most applications being written now are only required to support IE7, Firefox and Safari. IE6 is a horrible browser and usually requires a lot of extra coding and hacking to make things display correctly. The overall consensus in the development community is to try to push people to upgrade to IE7 so that support for IE6 can be phased out as quickly as possible.

Washington Post recommended upgrading away from IE6 in September, 2007
