The advantages of Project Rome
Compared to Handoff, the Project Rome approach is broader and not wholly locked into a single vendor's ecosystem. (We'll see if Microsoft actually treats iOS and Android as equal citizens, of course.) Project Rome also handles more potential use cases than Handoff does, which may increase developer adoption of the technology. Those two aspects should give Project Rome an advantage over Handoff.
But from what Microsoft has shown so far, Project Rome could also be complex to develop, precisely because it can cover many tasks and handles both local and remote connections. Fortunately, Project Rome extends several existing Windows 10 APIs, so Windows developers can build on what they already know from Windows 10.
With Project Rome, I'm cautiously optimistic that Microsoft may realize the liquid computing notion more broadly than Apple has.
