Exactly. So do OnShape, using a desktop or Android app as a client. This is important because if it works as advertised I'm no longer tied to any platform - a Linux laptop or Chromebook becomes a viable option. Even MacOSX doesn't have all the main CAD packages available for it, such as Solidworks ( which package a company uses is often determined by its clients and suppliers).
It's worth noting that CAD (unlike video editing with its high IO demands) is suited to being run in the cloud - its descended from the mainframe / terminal model, multiple engineers may be accessing the same model simultaneously, and models hold commercially sensitive information that's best not held on laptops floating about the place.
Whilst charging customers per month is appealling to CAD vendors, it does open the door to competition who might charge per task, or per hour, which would work out cheaper for smaller companies for whom CAD is only a part of their work flow.
