That does sound like an incredible start. I fear that for the kinds of applications we&#x27;re talking about speed could be an issue. For instance, if the system has to respond to events it can&#x27;t control, queues of events can build up or things that are likely to be synchronized might not be etc. I feel like in many situations, you&#x27;d want to run at full speed for official tests though early testing could use an emulator. Of course, if you&#x27;re emulating a much slower hardware as you mentioned, the test is more realistic. ;)
