Can you make it run on my device xyz as well?
In order to understand the answer to this question you should get aquainted to open source development in general. Even though the whole idea of Ubuntu Touch is organized and driven by canonical it remains an open source project and is characterized and limited by the same constraints. The main work is done by volunteers and in case there is nobody yet working on the device that you would like to have ported then good luck. You can only wait (and hope) or start porting
yourself. You can also look if you device have already someone "working" on it. List of Devices
