SD card to SD card transfer?

  Hi All -
For those who want to *work* with a laptop in the field (not just 
backup), and can't lug car batteries around easily, one fairly new 
option is a Solar/Power Gorilla combo This 
isn't as high-powered as the Powerfilm, but I've been testing it over 
the last week and the charge is very efficient. As long as one's laptop 
isn't too powerhungry, one Solar Gorilla and two Power Gorillas should 
give a more or less constant supply for less than AUD$1000, and take up 
very little space and weight. Of course, a car battery would store much 
more power if weight isn't a big deal, and the Powerfilm 60w would be 
much better for mountainous or cloudy locations.
