According to InfoWorld IE 8 users aren’t for very long.
As of 8:00 am Monday, IE8 — released Thursday — held 1.86% of the browser market, down from a high of 2.59% on Sunday, according to market watcher Net Applications. The most likely reason for the decline is that early adopters of IE8 are switching back to the more familiar, and –at this point — reliable Explorer 7 browser.
I was never even able to download IE 8 when I tried Thursday, server timeouts, I guess it’s all as well, because I’d probably be in that .73% downgrading. I’ve actually tried IE 8 on Windows 7 beta and I wasn’t all that impressed, just looked like IE with a couple of new buttons. The whole web slice thing drove me crazy too. Every time you would highlight the little button would pop up and be overall annoying.
