I'm trying out Google Chrome, and I have to say, it seems a lot more responsive.
It doesn't seem all that long ago that I was trying out Phoenix (remember when it was called that?) and it was the best browser out there. I think Firefox was more or less perfect fairly early in its development. I can distinctly remember thinking, in the 2.0 days, "Why is development continuing? It already does everything it needs to do."
I suppose in 10 years I'll be posting about how bloated Chrome has become.
