Not to try to dissuade you from your decision because I think you've really wanted a Sony from the beginning and I think you will enjoy it but I have to ask, you really don't think people would recognize the name Amazon?
Did you check Amazon for the titles you were interested in?
The charger options you've mentioned are also available for the Kindle (I have the Gomadic charger and tips). The Kindle is small enough to travel easily with (there are folks traveling all over the world with their Kindles) and you'd have more control over the font size.
Good luck where ever you travels take you and be sure to have lots of reading material while you're there.
