Yet another common misconception popping up:

-- You can talk about the OSI model in the present tense

(That said -- yes, it is still useful as a set of simple terms for certain combinations of functions.
It is also still useful as a way to calibrate your gut feeling of what is going on in a network.
Just never expect OSI terms to have a precise meaning in today's networks.  
1978 is now a third of a century ago...
If you need precision, you need to spell out what you mean in today's terms.)
