What alternative browsers are available on Android? What are the browser alternatives on Android and what are the main features that they offer?
Some options:


Coco
Dolphin
Opera Mini
Skyfire


Here's a quick read on AndroidApps.org that gives overviews on some of the more popular browsers. And a longer one from PC World.

I personally just use the stock Android browser. I've used Dolphin HD for a while, but at times it felt slow (on my Droid). The Opera Mini browser is supposed to be pretty quick at loading pages because it will transfer your requests through Opera's servers first so that they can compress the content and send it back to you. Right now, I'm waiting for the release of Fennec, by Mozilla, which will hopefully be amazing.
