I never really use IE either, unless I absolutely have to. If I need to test webpages with IE, I'll use
the IETab Plus add-on installed in SeaMonkey. The only thing that would prompt me to install IE9
is for any additional security the updated version of the Trident engine might offer. Other than
that, I see absolutely no reason to install anytime soon, if at all.
As far as the tabs thing goes, at least they can be moved from the stupid default position next
to the address bar, down to the more sensible position of below the address bar. I'm surpised
the IE boffins didn't offer the option to move the tabs above the address bar, although I'd
hazard a guess that'd make IE9 look too much like Chromium, and that UI is bad enough!
I'd go as far as to say that the UI of IE9 isn't just dumbed down ... it's FUGLY!

SeaMonkey = Swiss Army Knife: It's versatile, reliable, and contains useful tools.
Windows Internet Explorer = Old Swiss Cheese: Full of holes, and it stinks!
