I have been using Dropbox for some considerable time, but recently have looked at the product more seriously. The app allows you a good amount of free storage, plus bonuses for referrals.
Dropbox enables me to reduce, eliminate, reliance on USB sticks and external drives. Ease of use is excellent.
I can access the app via the web, plus I have the Dropbox client installed on my iPad Mini, Smartphone, personal laptop and my backup laptop. It makes storing, accessing and handling data of all types so much easier.
Should you decide to try Dropbox, please use this code http://db.tt/Sz0zjOD5 , as we will both get some bonus free storage.
