Those that are using cameras with SD cards, and trying not to carry a laptop in the field,....how are you backing up your SD cards? I fully realize you can lock a SD card and move on to the next card in the field and hope you don't lose the card(s). But that is not part of this topic. Just talking about making a copy of the photos on the SD cards that you can bring back and import into your desktop Mac (or PC). Has anyone tried the WD My Passport Wireless product? Looks like you can get it with a 2TB drive and set it up to either copy the files off the SD cards or move them off the cards. http://www.wdc.com/en/products/products.aspx?id=1330 I have seen SD card readers with integrated card reads over at B&H. But they are mostly in the $600-$1000 price range. With the My Passport Wireless I should be able to copy the images and then put into my iPad to see the images. Just wondering if anyone has done similar.
