So, the new iPad looks like a cool tablet for photographers. At least, it has the potential. My doubts are: 1. Can you connect an external drive to the iPad? This would be amazing to make photo backups in travels. 2. Can the iPhone OS read RAW files? If yes, does it have the sufficient capacity to display them smoothly? Somehow making a stripped down version of Aperture for the iPad would be cool, and being able to import to Aperture and then transfer them to you Mac would be cool. 3. Lastly, does the accessories for the iPad to connect SD card work with the iPhone/iPod Touch? Thanks.
