Microsoft isn’t going to force anyone to use the cloud desktop. It’s a product for businesses, and it’s probably going to be great, by lowering the cost and removing need to host and manage onpremise servers. The users won’t need to use a VPN or go through a RDS gateway that looks like it belongs in the year 2004. All they would need to do is login to their pc or the office-portal to reach the remote desktop. Remote desktops/applications are great, because a lot of users are not good with saving files/documents to a central storage, and you remove the risk that the hardware is going to fail and files be lost.
