The Importance of Right-Left-Up-Down Standards in Product Design

Yesterday I created a meeting on my Android smartphone (Galaxy Nexus running ICS), filled in all the details, invited a couple of people, and then accidentally cancelled it. I had one of those "WTF just happend??" moments. So I came back to the screen, and I noticed that the "Done" button was on the right and the "Cancel" button was on the left.
