on another machine" or whatever the term people use is).

A string represents all information about the device? that doesn't make sense.

Wasn't this supposed to be an ID into the devices API?

[Kristen Dwan, 2013/08/12 15:11:30]

Yeah (this is just a temp placeholder) - it will be the linked
signedInDevices.DeviceInfo. I put a note up in the description. should have
included it in the pub & mail too. Was waiting on lingesh to get the code
checked in for that. Will mail out the addition of DeviceInfo information after
I finish this up.

A list of open window sessions for the [adjective] device, from most recently to
least recently changed. [something about the number of sessions].

make this first parameter an object with argument properties:

session.getDevices({
  maxResults: 6
}, function(devices) {
  ...
});

is forwards compatible, whereas

session.getDevices(6, function(devices) {})

isn't. For example, one thing we might want to implement here is paging, which
would be configurable via other properties of the options object.

"and within each device..." that documentation should be part of the Device type

"The API provided" sounds awkward.

I wonder whether this should actually be an object with a window and a tab,
since if we're dealing in abstract session IDs here (which - we can, clearly)
there isn't a non-hacky way to tell the difference.

In fact, you could just return a Session object.
