Must every hardware firm make it's own iCloud clone?

Yes. It’s the new rule, it seems…

It is the dawning of the age of cloudquarius. Acer, in addition to a set of ultrabooks, just announced something it’s calling AcerCloud. This service, like iCloud, brings all of your content onto all of your devices, allowing you to “create, acquire and consume on different devices.”
