There's a lot of lies in this article...
"functionally inferior Internet Explorer 6"
Bollocks. At least IE 6 worked. There's nothing "functionally superior" about a browser that cripples the machine it is being run on. The entire of Stafford University suffered with a state of only being able to run IE7 exclusively - any other applications became unusably slow.
"benefits of faster speed, improved usability"
Speed - please see above. A browser that clunks along and takes over 1 second to open a new tab is not faster. The improved usability is a sick joke, and you know it. What's the first thing someone says upon starting IE7 for the first time? "What's this? How do you use this?" Every. Freaking. Time.
"with a constantly updated list of malware sites to protect the user."
We all know Microsoft does not know/understand how to make a file grow by addition. When a patch for a patch comes out, you're looking at two full downloads rather than one large followed by one small. How long before this list is over 100MB? AVG itself spouts that 1 in 1000 sites are malicous, that's going to be one very big list in a very short time. Even if MS gets its head around file appending, can you imagine the download after a format? Anyone on a capped internet is going to run out of space quick sharp.
"relatively simply task of inserting a tag in their code in order to render pages in IE 8's default standards mode"
This smacks of complete ignorance. Many of the blue chips need to go through many, many steps to make even the smallest changes to their websites. Even intranet pages need to be checked, tested fully, signed off, seconded, rechecked and confirmed before you can correct even a spelling mistake. And what if we do give into MS and add <ie8 />? How long before <ie8.5 />, <ie9 />, <ieInfinitum />? How about they build a standards compatible and make OLD sites append a <ieisshitandthissitewasmadetoworkarounditsousetheoldversion /> tag?
"IE 8 is more secure than Firefox, Chrome, Safari and Opera"
I think you know as well as I do this is the biggest lie in the article.
