One cool aspect is that it runs entirely on the phone and has a web interface for programming apps. This makes it platform independent and is actually true to Steve Jobs’ original vision of an entirely web-based application stack. I just don’t think he had this in mind, though.
I tried to build an app but it wasn’t saving my meta-data, which makes baby me cry. However, the ‘Hello World’ app seems sane enough so I’ll give it a go later tonight.
