I was on a mission to see what is the best cloud storage for my personal use. Thus, I have tried the following solutions:
I am not going to delve into details, but I have found that Box is the best one from the list. It has a powerful interface and you can do a lot with it, plus it gives you the option to view offline files on my iPad (SkyDrive does not have this functionality). There are a lot of vendors out there that offer free cloud storage, but Box is the one that I use most.
