Identify traffic of iPad mini

[#1]

Is there a way of differentiating traffic of iPad mini, using the reporting interface?!
Are there plans to differentiate this traffic by device?

As you probably know, we are limited in our ability to detect mobile/tablet devices by the user-agent string and other HTTP headers that are passed in the image request; at present, the iPad mini has the exact same user-agent and headers as the "big" iPad, which makes it impossible to detect the mini as a different device. We are working with our mobile device lookup vendor and Apple to change this in the future, and as soon as it's possible, we'll do it.

Are you able to differentiate the screen size?
