Microsoft has updated SkyDrive to support Windows desktops, OS X and iPad -- but at the same time has revised the storage limit from 25GB to 7GB, unless you claim to reserve the existing 25GB limit.
Users of Microsoft's SkyDrive who signed up when the service offered 25GB of storage will need to log in to their accounts to retain their current 25GB limit, as Redmond has announced a revision of the storage limit for all new users to 7GB.
If users want more than 7GB, they will be able to upgrade to 20GB, 50GB and 100GB for US$10 per year, US$25 per year, and US$50 per year, respectively.
Microsoft says that only 0.06 per cent of current users of the service use more than the new 7GB limit, and any current users who are using more than 7GB have been automatically moved to the 25GB limit.
Beyond the change to the storage limit, Microsoft announced that SkyDrive applications would be made available for Windows 7, Vista, XP, Mac OS X, and an iPad app with support for its Retina Display. SkyDrive is already integrated into Windows 8, and is available as a mobile app for iPhone and Windows Phone.
In other Windows news, Microsoft has today announced that the Windows 8 release preview will be available in the first week of June.
