When I went to Australia, New Zealand, and Venice Beach, I took my camera, two or three lenses, and my iPad with me at all times. For the iPad, the Camera Connection Kit is the essential gizmo. For those of you using SD cards, that's all you need; if you use Compact Flash, you'll need to plug a CF reader into the USB port the kit provides. I haven't researched other memory formats, but I'm guessing Sony's would work similarly. I have a 16GB iPad, so, as a practical matter, I only have 8GB memory cards. After all, I want to be able to load in ALL my photos. If I make sure my iPad's no more than half full at the start of a session and only use one card's worth, I'm good. I tend to review pictures fairly frequently: every couple of hours, more if I have the opportunity for some re-takes if needed. In Venice Beach, I imported over lunch, and reviewed my pictures. I delete the ones that are seriously out of focus, but I've learned that I'm not looking at the full-res version of the image, so I try not to make decisions about whether or not picture A is in better focus than picture B. I'm just trying to whittle out the spectacular failures (of which I have many, especially if I'm trying manual focus). At the end of the day, I sync back to my laptop, which is when I make the decisions about focus. I do that in Photoshop at 100%, so that's pretty time consuming, but I can usually weed out a bunch even before that.
