"Dulaney also noted that updates would be more frequent, more incremental, and less obvious to the end-use"
I think this is where the major leap is going to be. Microsoft has claimed that there will be no future versions coming up for Win 10. All the improvement in the OS is going to take place via the updates and users will have to download them from time to time. This implies that MS is expecting that no workstation will ever work in an offline setting and will have internet connectivity of some sort.
