If you had the ability to back-up photos you have just taken on your camera wirelessly, would you want to make use of it?
(including both point and shoot & dSLR)

Please reply with 'Yes' or 'No'
And if you could include the camera you have too.
Either make & model...or 'PS' point & shoot, or SLR (for digital SLR)
If you use a system already please inform me of what it is, if you have issues with it please name them, both pro's and con's.
