This product suggestion comes from one of our customers that uses tablets to document building conditions while rappelling from ropes. Because their work requires a higher level of photo detail than can be found in a Tablet PC, they need to use a 12MP digital camera. When you are hanging 15 stories about the street, tethering your camera or transferring an SD card isn't really a practical solution.
What they did is find a product called the Eye-Fi (www.eye.fi) which allows them to wirelessly transfer photos from their digital camera directly to their tablet PC so they can mark them up.
If you try this solution, let us know how it works for you.
