OneDrive has opened it’s doors today. The new brand is still rolling out as we speak, so when you still see the SkyDrive logo on http://skydrive.com (when loggon on) you’re not yet ‘migrated’ to the new environment.
At this moment the new ‘co-owner’ functionality isn’t available yet, but there are some new Upgrade Options available when you’re on OneDrive. On SkyDrive you could upgrade to a 50GB, 100GB or 200GB plan.
OneDrive gives you some more options : 50GB, 100GB, 200GB and 500GB. Next to the ‘normal’ upgrade options, there is also a Special Offer available : Office 365 + 20GB OneDrive Storage. Office 365 Home Premium includes 20GB of OneDrive storage for each household member (up to 5) and the latest Office applications for 5 PCs or Macs and 5 mobile devices.
At this moment the 500GB option isn’t visible at my own OneDrive, but this will probably change soon.
