I can get Office 365 Family (6 people), each one getting 1TB, plus 60 mins of skype per month each, plus word, excel, PowerPoint, online and desktop. Dropbox's Family plan, includes only 2TB of storage and basically nothing more (I know about paper but who uses it?). Office365 costs 50 euros per year. Dropbox 200 euros per year! Four times as expensive, and much less features. They are crazy expensive.
