Programmer vs. Developer ...

Somebody once asked me what the difference was between a programmer and a software Developer. Is there any difference ?...I answered following:

Programmer: A biological machine designed to convert caffeine into code.

• Is someone who does nothing but code new features or fixing bugs
• Someone who, if given a complete functional design, task, can code huge systems and do it extremely well.
• They don't write specifications.
• They don't write automated test cases.

Developer: A person who develops working systems by writing and using software.

• People who will contribute in multiple ways to make the product successful
• A developer is the complete package.

To be more clear....I am a programmer and my wife is a developer.
