Uh huh... is the PS2 obsolete? It sells better than the 360.
It depends, obsolete when it comes to technology is mostly used to refer to technology that is still used in current production and not whether or not people are still using the product that uses that technology.
I mean people are still driving around with cars from 30 years ago that doesn't make all the technology in those cars current. When was the last time a mass produced for everyday civilian use automobile came with a carbuerator.
