I've playing with this browser for a few minutes and I can already tell they made some big improvements(but have a lot to go).
The Good
1. It feels a lot more responsive than it did before.
2. New font smoothing setting looks a lot better than before. Now looks exactly like every other browser.
3. Spell checking and Grammar checking.
The Bad
1. No way to block ads that I've noticed
2. Still eats up more ram than others(150mb right now! )
3. slow to load home page but after that it flies.
I wouldn't use this over IE7, Opera, or firefox but at least its another option to those who dont like those.
