If you install Ubuntu with Unity, you can’t easily change your desktop
Not strictly true. I installed cairo-dock. From the log-in screen(14.10) I can select cairo-dock which does not contain Unity. I love it!

If it is not strictly true, then it isn t true at all! In normal Linux, you could install exactly any desktop you want, many of them, and switch back and forth between them at log in. You can certainly install different desktops on Unity but not without consequences.
By the way, what version of Ubuntu are you using?
