Pandora needs to stay at the top of the music one, no matter how many similar products we get. I would like to see a BBVA Compass Bank app, but they aren't really leading the forefront in apps, anyway.
Southwest Airlines (the Android App works very well)
Dolphin Browser HD (I dont know if we can have a browser as good as that but Ive never used a better browser on a mobile device than Dolphin)
ESPN Fantasy Football
As far as the browser goes, I guess were are going to be out of luck unless MS will allow a company to create a native browser. I think right now, any browser other than IE is just IE wrapped in a different looking package. I have a feeling MS is going to be stingy and we'll never see a completely different browser
