Here is what I do: I import pics into the iPad via iPhoto. I have tried other programs but I iPhoto to rotate, crop, email, cull, etc. in jpeg. Later I download the pics again into Apreture on a Mac via SD card, etc. The pics that are ultimately in my permanent library do not pass through an IOS device nor PhotoStream. The iPad is a great device that to see, review and share pics but to use Aperture and Photoshop you still need a MBP, MP or iMac. IMHO.
