I will admit, however, that it sounds like an iPad or similar tablet has changed this equation, bigtime... Everyone I know is telling me I NEED one, and it's just a matter of time before I go down that road... We shall see, but I still think I'm too much of a dinosaur at this point to ever be comfortable without the appropriate paper aboard... :-)

I found the same thing with a macbook. Someone correct me if I'm wrong here, but looking at the chargers;

macbook input @ 115 volts = 1.5 amp
Ipad2 input @ 115 volts = .15 amp

Then you can take the ipad further using a 12v charger, no converter. It charges at half the amperage.

Where as the macbook was a charging issue on my boat, the ipad is a non issue. For you with refrigeration, it's an undetectable usage.

Nice photo! When I first met you on the web, you were railing against digital cameras and the demise of film. (grin)
