If you're shooting raw, does an iPad or other tablet have the capability of working with RAW files, or does this limit you to jpeg?
Nope it is Jpeg only. I have an eye-fi card - it is a good solution for jpeg only shooting, but if you regularly shoot raw+jpeg the card would fill much too quickly (not to mention raw file transfer takes a lot longer due to file size). I used to use it in my olympus e-pm1 which was my go-everywhere camera, now I use it in the 2nd slot of my d600, writing raw to a 64gb card and jpeg to the eye-fi pro x2.
A lot of newer cameras have the ability to detect (or setup so the camera knows) that an eye-fi card is being used. From my use this seems to get the card to broadcast its signal and be detected faster than on cameras that don't have the card detection. the e-pm1 and d600 both have eye-fi compatibility programming like this, not sure if the k-30 does? (edit:
it does not have eye-fi features) The difference I found is that the app I use (android version) will start itself, vs with a non-eyefi camera I would have to start the app myself. If you're shooting randomly it can take awhile if it loses the card connection like that often.
Speed is decent, d600 files are under 15 seconds transfer, usually 6-8 if the app is running and connection going - to my android phone (they are more than 20mb files usually). I have it setup then to transfer to my PC via wifi only, so that it only does it when I'm home. In between using the card, when connected to 3g my phone will also upload a downsized copy to a private folder in picasa (it will create a new named monthly private folder on picasa each month as well - actually you can set it up to create new folders daily, or however else you might like).
