Claudecat, Wayland is purely on the back end, it won't make a bit of difference to the end user (except for greatly improved performance, of course). X11 is outdated, the top feature of X11 is that it can allow you to run applications over a network, which no longer has value, since the modern standard is to just write a web application that can be run in any web browser.
Future releases of Unity are mostly just bringing some 3d Compiz bling to the desktop without requiring the user to learn 1000+ hotkeys to initiate the FX. This lowers the barrier to entry for being a L337 Linux g33k with a desktop cube that spins around. Besides, it's just another taskbar to click on, there's not a whole lot to get your head around.
