Sorry... should have added that I already have a Eye-Fi card. Just curious hoping someone who has been there/done that might be able to offer some insight.
My guess is that the Eye-Fi card, however minimal, is going to draw power constantly. The internal can be shut off when not in use. Then again, the Eye-Fi could be dormant until an image is sent to it. Just don't know enough about the two, so I ask.
