I like that everything is stored together so you can search for things easier than having to go through each of your different services separately (Dropbox/Google Drive).
Also being able use multiple devices at once makes life much simpler with files! Sometimes when viewing my Google drive from another computer or phone will cause issues where certain pictures are not shown properly but this seems fixed now after updating their software last month? Not sure if its just me though as other people have said they don't seem too bothered by these problems either which leads us back agains google's explanation about how easy sharing between computers has become since launch - however i do think there could be an option somewhere within settings allowing more control over what information gets shared without everyone knowing who accessed them first etc.
