Coming from my D1, I was using Opera exclusively. The reason for this is the intelligent content formatting.
Ever notice when visiting sites like this one that the text runs off the screen? Not with Opera. It always takes the content you are reading, resizes the paragraph widths and fits it into whatever zoom level you have on your phone. Brilliant! But Opera has a slow loading time, every time you use it. Not-so-brilliant.
I am still using the stock browser on my Bionic, but I sure do miss that formatting. I never observed this functionality on other browsers, but maybe some do this now?
