In a brilliant move, Sony has pulled the plug on their cheaper 20-gig PS3 model. All the better to concentrate on what consumers really want!
All sarcasm aside, there was never any reason to have the $500 20-gig system except to help muddy the price-point waters at the time of launch. It's a rump system with no wi-fi, limited connectivity, and, if memory serves, limited backward compatibility, too. If you were going to spend $500 on a PS3, you might as well shell out the extra $100 for the full system.
