I thought that first. With the exception that they exactly leave the Onedrive storage class (1TB, 60$/year) out. If you are happy with 200GB, the Google offer seems to be a lot cheaper. If you need up to 1TB, you pay twice than for Onedrive. Theoretically you can even count Office 365 Home as a 5TB, 90$ option, which makes it even yet cheaper. However that's a bit more of an unfair comparison, since it would involve the hassle of using multiple accounts (and I'm not even sure if the Onedrive app would allow that on a single installation).

I think that microsoft did really good job with their Office 365 home package.

Each of the 6 accounts gets: - 1TB for OneDrive - Office licence - 60mins for Skype - 50GB for Outlook

Initially I wanted to go with the Google Drive because I'm using Android, but after trying android and mac one drive clients i decided to go with one drive.
