the real difference, is that structs, being value types, are 
passed by value, and classes, being reference types, are passed 
by reference.

this is the most important difference to be aware of.

where they live in memory should be less of the programmers 
concern, and more an implementation issue (although some 
programmers will of course consider this as well).

btw. where does a struct, inside a class live?
