I am a photographer and I'm taking a 3 week trip through Italy soon. It would not be unusual for me to take 5000+ photos. For the first time, I'm leaving my MacBookPro at home and taking my iPad (4th generation). I have 108GB left of iPad storage but I don't want to leave my photos on the iPad in case something happens to it. I've been researching iCloud and Dropbox but can't figure out which one would be the better choice. I'm also going to be writing articles along the way but I work in Word. Neither seems to accept Word docs. I also have OneDrive on my iPad - it seems to accept photos and docs - but I've never used it.
