I totally agree and Cesium is a really cool project and I encourage people to check it out (the number of interesting applications they showcase is really impressive). Just proud of what our team has come up with and wanted to share.

Navigation/Rotation is inherited from the original Java based World Wind in an effort to provided similarity to users wishing to change platforms. A little different from the arcball-style, I agree, but at least there is a reason :)

There are plans to add momentum gestures to our Android platform (https://github.com/NASAWorldWind/WorldWindAndroid). Perhaps it should be added to the Web version as well?

There is a mix of imagery in the public domain and available through commercial providers. You can even specify your own WMS source!

Interesting note on the elevation model, if you've got a second, can you open an issue on the github site with a screenshot of what you are seeing?

Don't mean to hijack, but if you're interested in 3D globes (and 2D projections), NASA has been working on porting World Wind to Web:

The power of WebGL is awesome!
