The Emacs meta key is especially weird as it depends on the keyboard  
and your environment. E.g. on a PC running a graphical interface, the  
Alt key works ok if you press it simultaneously with another key. When  
running in a terminal, Alt may not work, and you have to resort to  
pressing the Esc key as a prefix key, followed by the next key. The  
former might be represented as:


whereas the latter would be something like:


So even if you would move away from the key caps to not depend on what  
is printed on the key, you'd still be wrong about pressing the keys at  
the same time or one after the other in 50% of the cases. But I also  
think if you're writing about Emacs for end users, the key caps are  
what counts.
