We got my mother-in-law an Acer Chromebook & she's very happy with it. It comes with some some internal storage but is largely designed to work with the Google Drive (you get extra storage free when you buy a Google laptop or box). It has the advantages that it boots up very quickly & all the virus software is handled automatically by Google. I think it's safer to store your photos on cloud storage than on your own hardware anyway as the big companies back their stuff up every night so your photos & vids should be safe. We use Flickr as they now give you a terrabyte of data free, their upload tool is pretty efficient, they allow you to upload your photos at full quality automatically & don't mess about with your security settings (like certain famous social networking sites).
