Supposedly, IE8 will be "more compliant with web standards." I have not tried it - from what I've read, it has a "porn mode" (or is that a "safe browsing" mode
) like Safari, an Awesome bar type feature (like FF3), a tab grouping feature and a 'web slice' feature.
I'll wait for the next beta or the release version before I try it - unless the overwhelming opinion here is that it is a "must have" - hence, the topic.
I have used (and felt secure with) FF for a long time and suspect that IE8 won't make me want to change from the then current version of FF - whenever IE8 is released. I'm waiting for the MS announcement of release date so that I can add a year or so to it!
