o365 home is $99.99/yr (not $50/mo), and allows up to 5 users, each of whom gets their own 1TB OneDrive allotment, evergreen desktop and mobile office software, skype minutes, etc.
It's a much better deal than paying $80/year for 1TB of OneDrive if you have 2+ users.
Dropbox and Google Drive both removed HTML hosting over the past few years. With drive you can't even get direct links to images etc anymore. Not sure if public Dropbox files have the same limitation.
