The way you make users understand your program model is with metaphors. When you make things look, feel, and most importantly, behave like things in the real world, users are more likely to figure out how to use the program, and the app will be easier to use. When you try to combine two very dramatically different real-world items (email and appointments) into the same kind of thing in the user interface, usability suffers because there’s no longer a real-world metaphor that applies.

A corollary of this is that you can't move a UI layout from one platform to another and have the computer make everything fit. Computers don't lay out interfaces by themselves any better than they can translate French to English by themselves.
