You can use you Canon 60D images. However the 18 megapixel images willl be downsampled to maximum 12 megapixel. Please note that this depends on your Max. Import Resolution at Settings > Image import.
Is this something that is going to upgraded in the future? I use an Eye-Fi card to transfer photos to my tablet as I shoot, and I would love to use Photoshop Touch in the field to edit photos, but I cannot afford to have the images downsampled. (I am currently using a Nikon D5100, 18.1 megapixels.)
As phone hardware becomes more powerful over the time, several restrictions will be also loosened.
