The thing is that vim is actually pretty simple to learn. The arrow keys still work. in macvim you have a high level of usability out of the box with mouse support enabled, copy and paste from the system pasteboard using normal keys, etc....
Even if you are using vanilla vim you can learn the basics of how to edit a file to notepad levels in about 1 min. (command line vim "new file name", press i, use as a normal editor, press escape, press :wq)
vim -y starts vim in "easy" mode where vim essentially behaves like dumb editor like Notepad++ would. And even in terminal (at least in OS X with iTerm2) you get mouse support for cursor positioning and visual selections.
