I've been an iPhone devotee for awhile now, and so naturally picked up an iPad last week and have been having enormous fun so far
One practical example was a wedding I shot on Saturday. While the guests dined and I had a beer, I hooked the camera kit to the iPad and sucked in 513 photos....took 24 minutes for the jpegs (I shoot raw + jpeg)
The delight and amazement the guests then had (especially the oldest and the youngest) in handing it around for an hour was very encouraging. Of course none of the photos were edited in any way at all, but they hardly mattered
