It has 8GB, so for days out its fine, but for a long hols I dont think it would be able to keep all the photos - especially if I'm diving and shooting RAW. I havent had it out properly yet on a long trip so dont know how quickly I will fill it, but for days out its excellent, espcially when we've been away at B&Bs and not needed to take the laptop but can then still view the photos at a decent size on an evening. Its also really handy that ShutterSnitch keeps the albums (collections) on the iPad so we can take the photos to then show friends and relatives.
