Skyfire IS awesome. It plays videos that the regular browser doesn't play. I played a full COPS episode and 24 for about 20 minutes. Sadly, it started a House video, but cut off after about 5 minutes. But it shows promise...I'm still checking it out, watching a Bones show now. BTW, the videos I watched were on the mobile network, not WI-FI. Hopefully it will hook up and work with my SUV entertainment system via TV out.
Overall, the browser itself is far superior to the stock browser, IMO.
