Even though it’s very spartan, I would take the System 7.0 user interface over Yosemite’s any day.
While I did immediately downgrade my test systems off of Yosemite, I did install it onto a VMware virtual machine (this is how I’m going to test it going forward). This obviously is not the same as running it on bare metal but it’s better than not having something at a bare minimum for testing purposes.
