I have an old iPad and I am traveling with it instead of my laptop. Sounds like a fine idea as it is light.

I bought the camera connector which effectively allows me to plug the camera memory card into the iPad, and it also comes with a connector to plug my iPhone into the iPad to either transfer photos or use my iPhone as an Internet server on the mobile/cell network, instead of using the mobile wifi, which drains more iphone battery.

So the photo selection works well, and I had downloaded an iPad app called GoFunky which does reasonable basic editing and is free. Bonus.
