This is pretty funny and normally I would agree, but IE10 is promising.
download their "super alpha" version of it.
It has html 5 support, css 3 support.
It has tons of new features, and it runs background scripts seperate from UI so it does not appear to "lag"
It runs really fast, and It might be an aweseome browser.
I just do not like the lack of customization for the IE series.
But all browsers will update for competition, so we'll just have to wait and see what the new firefox, chrome, opera, ie, safari etc. have to offer in these upcoming months.
