RE: Core Device APIs

Why don't we instead use the dom style methods such as
addEventlistener() and removeEventlistener for async operations compared
to pendingOp style? I say this because developers are used to then well.

Functionally, are they any different?

Hi Robin,

fwiw, geolocation wouldn't use device.cancel().  in some of our early
discussed we had a notion of cancelAll() that would cancel all pending
geolocation requests.  To make the API simpler, we dropped this form.
Instead, every call to cancel needs to pass a request id:

var watchID = navigator.geolocation.watchPosition(successCallback,
failureCallback, null);

Other APIs that we have discussed in the Geo WG have been accelleration
and orientation.  In both cases, we have been considering using dom
style events (addEventListener) and the right way to cancel in this
model is to just call removeEventListener.

If people agree, this is a contender for swift publication.
