Mcgrawfan, we are considering purchasing either a Nixvue or a digital wallet - there are three digital cameras in our family, and we think this would be an easier way to deal with the storage issue.
When we have gone to WDW, we always take the laptop and a burner and then spend about 1/2 hour in the evening downloading the camera.
The Nixvue has some great software that allows a lot more flexibility, including viewing on the TV screen in the stateroom! And the best thing is that either of these are portable (10 ounces) and you can just download on site.
You can see the Nixvue at its website. (You know we cannot post links here unless they link back to the disboards.)
