The truth about Ubuntu Unity is not what you think
Let's face it, modern interfaces are all really easy to use. So let's call it like it is...a matter of taste. You either like Unity or you don't. You either like Windows 10 or you don't. Both, however, are user-friendly, intuitive, and do their jobs well.
If, however, you do find Unity (or Linux, for that matter) challenging...you might want to rethink your career of choice. Harsh words? Maybe. But if you're in IT, a user interface should be the last thing to confound you.
