Internet Explorer 6 was released in the year 2001 and since then, as is well-known, Microsoft has redesigned Internet Explorer from the ground up, with better security, new capabilities, and a whole new interface.
Many changes resulted from the feedback of millions of users who tested prereleased versions of the new browser.
Why should I upgrade to Internet Explorer 7+ ?
The most compelling reason to upgrade is the improved security. The Internet of today is not the Internet of seven years ago.
There are dangers that simply didn't exist back in 2001, when Internet Explorer 6 was released to the world.
Internet Explorer 7 or 8 makes surfing the web fundamentally safer by offering greater protection against viruses, spyware, and other online risks. Naturally, we recommend the latest version IE8 as best solution.
Quoting Computer security researchers from ETH Zurich, Google, and IBM:
"The issue of browser security matters more these days because more and more malware is targeting Web browser vulnerabilities. Remotely exploitable vulnerabilities have been on the rise since 2000 and accounted for 89.4% of vulnerabilities reported in 2007, according to the study, which claims that "growing percentage of these remotely exploitable vulnerabilities are associated with Web browsers." Among the various Web browsers studied — Internet Explorer 7, Firefox 2, Safari 3, and Opera 9 — Firefox 2 is the most secure, according to the study. Firefox 2 is considered to be the most secure Web browser because 83.3% of its users worldwide are running the most current version. Second, third, and fourth places go to Apple Safari 3 (65.3% of users running the most current version), Opera 9 (56.1%), and Microsoft Internet Explorer 7 (47.6%)."
So, why does still people use IE6?
We don't know why, but we strongly believe that it is lack of information.
But should WebDesigners not produce their websites to reach most of the internet users?
Yes, that is absolutely true. But it is also true that WebDesigners have the duty to create and release their work in the most advanced and secure conditions.
