Rob Eisenberg's back…and this is his enhancement to IT:AD:Durandal.JS
Notes
Advantages:
Rob's a great architect and his work is solid.
Considerations:
I don't know yet if it still is IT:AD:System.JS based for everything, or whether files can be preloaded, and therefore shoe horned into IT:AD:PhoneGap.
Disadvantages:
He's stating very clearly that it's for modern browsers. Ie…IE6, no way. Has mentioned that some people have got it to work on IE9, but I don't see it a good fit for enterprises at this point (Spring 2015).
