Skyfire has a very neat trick when it came out: it intercepts the various Flash Videos on webpages, transcodes them, then feed it back to you. As such, it is the first browser EVER on Android to play Flash Video, even before Flash became available for Android.
Obviously, this ain't cheap. Videos have to be downloaded, transcribed, then optimized and sent down to you. This cost money. So Skyfire is free... but the video optimization thing cost $$$. You get to try it for 3 days, and that's it. After that, pay $2.99 to unlock.
Skyfire, fortunately, is a very decent browser that has a couple OTHER tricks... Twitter and Facebook Integration, for example, plus RSS Feed Reader built-in, and better toolbar than ever. Is it enough to get you to switch? I don't know. But at least, try it. You may never go back.
