Apple's iCloud storage-and-sync service has had a rocky history since its October 2011 launch. Developers continue to gripe about the problematic iCloud API and the service's sketchy syncing skills. In addition, critics are questioning the Apple-centric nature of iCloud, particularly when strong competitors such as Dropbox, Google Drive and Microsoft SkyDrive are better options for cross-platform computing.
Lest we forget, WWDC is a developer's show. It's the ideal platform for Apple to announce improvements to its iCloud API. As for expanding iCloud's cross-platform capabilities, Tim Cook put the kibosh on that idea at the D11 conference, saying it doesn't make sense for Apple to do so now.
