I see there files created few days ago, and I wonder, why in July 2011 people and corporate will stilll choose to use IE6/7/8 when FF/Chrome/Safari available for Windows, for free, and support all or most advanced, neat HTML5 features
Should not corporate care most about information security? How can they let instances of those versions of IE in an organization's network?
The question then becomes whether to upgrade the application (with a massive price tag), or keep their old version of IE as the standard (which appears to cost nothing). In fact, there are costs of maintenance and security, but those aren't readily apparent on the balance sheets.
These are stupid reasons, but they are enough to prevent companies from upgrading.
And consider the users as well. These are corporations with thousands of users with no technical expertise, especially corps in fundamentally non-technological fields like say education or food service. These are the users with twelve handwritten steps on Post-its for how to open their timesheet on the intraweb. Even a switch to tabbed browsing can get them lost in their routines. What IT department wants to spend any amount of time upgrading and retraining these users?
