I like the hardware design and I like what I've seen of the UI so far.

Microsoft makes most of their money nowadays from Office subscriptions. If these guys hope to survive, they need to be clear about their monthly subscription costs. If Joe Public are already paying $99 a year for an Office subscription that also gives them 1TB of cloud storage then these guys need to come up with something that can compete. Finland's F-secure already tried the cloud storage business with Younited and failed.
