I don't know much about virtualization technology, but Docker is nice for me because it's an accessible, well-known, and rather easy way to make applications easy and straightforward to run.

Where I've worked in the past, setting up a new development or production environment has been difficult and relied on half-documented steps, semi-maintained shell scripts, and so on. With a simple setup of a Dockerfile and a Makefile, projects can be booted by installing one program (Docker) and running "make".

You could do that with other tools as well, but Docker, and even moreso the emerging "standards" for container specification, seems like an excellent starting point.
