According to Google Analytics, when I sort by device and then add screen resolution as a secondary dimension, none of them are ipad3 or ipad 4, they are all 768x1024, which is ipad2 or mini.
If I can't segment by device, I don't know what my visitors are seeing. I'd like to know how many are now using a mini versus the ipad2, 3, 4.
If anyone's interested in their own visitors, it's to be found at Standard Reports > Audience > Mobile > Devices > (secondary dimension > Technology > Screen Resolution)
Is anyone else seeing a bigger screen res than 768x1024? iPad3+ (retina) ought to be a high percentage of ipad users.
