The PSP to date has sold about 40 million units. The PS3 on the other hand, at 17 million units, lags behind its other console competitors such as the Xbox 360 and the Wii. Sony has been trying to boost its sales through a variety of factors (that don’t include a price drop). In my opinion, Sony needs to hurry up and implement the feature that will allow PSP users to play games on their PS3 on the go if they want to boost their sales. After all, it has the potential to turn a big chunk of their PSP base into PS3 owners as well. Sony can learn a thing or two from Apple with regards to hardware interconnectivity.
