A few days ago I said for you guys to update your browser to make web developers life easier, but it seems that IE8 is following his older brother steps, at least until now (RC1 version), which means that web development is about to become more challenging.
I was hoping that IE8 would significantly reduce the number of brave/stupid/I don’t know why someone still use this crap IE6 users, however, I must confess that I am concerned with the idea that IE8 could cause even more headaches. Some issues are reported by Michael Dayah (from ptable.com), who described some problems while trying to render elements that Microsoft is marking as “won’t fix” and also kangax, that reported that a single JavaScript line can crash the browser.
Besides all that, IE8 is still the slowest among big browsers (almost 35% more than the second slowest: Opera), of course that Microsoft continues to dismiss benchmarks like this. Anyway, who cares about performance? Do you remember Windows Vista?

UPDATE: MSDN provides a lot of information regarding the migration to IE8 tha you can find following this link. Some informations provided are very useful, such as if you find some issue that you can not fix or find a workaround for, you can make you page to be rendered as IE7 placing the following HTML META tag into the HEAD element of each Web page (before tags other than TITLE or META):
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7"/>
