If there's an "ansible.cfg" file in the current directory, you can put "inventory=inventory.ini" in the "[defaults]" section and not have to mention it on the command-line.
Instead of saying "--sudo", you can put "become: true" into your playbook file.
That makes the Ansible command-line a bit simpler, but still not quite as simple as Fabric.
In my experience, Ansible really shines when you have modular configuration, where these hosts need this subset of configuration applied to them, but those hosts need that overlapping-but-not-identical subset of configuration applied. Using Ansible for configuring a single thing on a single host is overkill for production, although it's a good way to learn about it.
