Although the UI is entirely responsible for what many refer to as the "look and feel" of an operating system, it really has no bearing on how things actually work under the hood. End users tend to dramatically overemphasize it's role (although it certainly is an important role), as it's typically the only part of the OS they directly experience. Overall, the UI is an extremely small part of what makes an operating system "tick"... in terms of functionality as well as in terms of the effort required to "conjure" an OS into existence. In fact, many large and complex operating systems exist that have no user interface at all.
