Just as a curious question, why Promises? Most of that information is static, so everything is already known at the time of creation and returning said DeviceInfo object should be instant, if not in constant (and very short) time.

The only case where the promise makes sense is if the context has navigated away from the initial URL (if I understood the design correctly) but if it's a synchronous API, this would be a security violation so throwing would be perfectly appropriate. (Additionally, this simplifies the implementation for implementors who will be implementing this with say, addJavascriptInterface())
