I find it somehow odd that often many people equal good UI with easy to learn UI. They _can_ be the same, if we have an application that is rarely used more than once, but for an application that is used often and a lot, they typically seem to be very different animals. Notepad has probably the easiest UI to learn while being as probably the crappiest text editor for any serious use with any significant installation base ever created. Vim is the other way round. It is extremely easy to do something with data using Excel. For any serious data management you are doing much better working with a database.
