Yeah, this feels like a "why do you need an IT department?" kind of thing. Just rent your computers from MSFT and they'll take care of maintaining them, upgrading, etc. "It's all in the cloud" and all that.

It seems like the logical end goal would be you pay your subscription fee to Microsoft and you just sign in and all your subscription-based apps and data are just there, in the cloud, always available. You stop paying, they'll all go away... or are limited in some way.
