That method only works, when you have the computer around all the time. It still doesn't solve the problem of importing only JPG files onto the iPad in the field.
I just purchased an iPad mini the other day for use on the road solely to check images, composition, focus, etc. and be able to show the client bigger previews during the shoot.
I did some research, but have never thought, that I would stumble so harshly over this stupid limitation with RAW and JPG import! I mean, these guys at Apple have a pro App like Aperture in the works and they can't think of a smart and quick solution for photographers to have a choice when importing pictures to the iPad? That issue should have come up in a meeting about camera connection to the iPad before the thing came ever to market as a product! Now we are at iOS 6 and still have to find work arounds, that all do not really work?
I would be willing to invest in Eyefi cards, if that system would work fast and reliable. But I read too many posts about it not being up to a fully professinal standard to use whlie a client is around. Replacing some 60 GB worth of CF-cards with Eyefi cards would run me somewhere around 600,- €. That is an expensive work around for a stupid little missing dialogue box popping up before importing photos.
I am writing all this, because I spent around one full day researching the net and discussions, etc. to find a half way elegant solution to this problem, that I never thought could even exist.
Conclusion: From all I found out until now, there still is no solution for this problem. So let's see, what iOS 7 will bring besides a simplified GUI.
