I like some parts of it, and really dislike others.

Rating:
2.5 stars
Fair/Good
Things I liked:
1. Cool new look.
2. Tabbed browsing.
3. New "anti-" tools.
Things I didn't like:
1. Some websites don't display correctly in IE7 (
www.jpfo.org, for example).
2. The zoom function can REALLY mess things up.
3. Rolling back changes from IE's official site doesn't work for beans (for me, at least).
Other things I noticed:
1. Still hasn't gone back to using cached copies (as Opera does) for quicker back/forward navigation.
2. No Opera-esque mouse gestures.
3. Opera already has tabbed browsing and a zoom function.
4. I know few people with less than 3 popup/spyware/etc. blockers simultaneously active, so one more seems redundant.
Conclusions:
It has some nice ideas, but they are hugely flawed. A browser that doesn't display sites correctly is like a phone that can't call some people, and a zoom that screws up pages is like a car that needs to be turned off and on again every time you mess with the mirrors. MS needs to learn from the Opera folks how to make a proper zoom function (that doesn't cripple an open page), and they need to learn from the IE6 folks how to achieve nearly 100% site compatibility. The only reason I'll keep using it is because I am unable to roll back changes.
