What is the best way to use an iPad while travelling?

[Reginald G]

Gavin gave you a good answer to which I would add the following....

You can open a Gmail account, which will give you a Google+ account. Google+ has a Photos section which contains fairly extensive editing capabilities that might do for your photos. You can set up your iPad so that the photos are automatically uploaded to Google+/Photos. The reason that you would consider this in addition to the editing is that it will give you an on-line backup of your photos "just in case".

In any event, be sure to set up some on-line backup setup for your photos and all on the iPad in the event it is lost, stolen or damaged.
