Of course, House is omitting most of the reasons that the PSP Go isn't the best value proposition. Sure, people like to collect and display game cases and other retail bonuses. But they also like buying games on their release dates, rather than several weeks later -- or not at all -- as is the case with many digital versions of PSP games. They also like having the choice between digital and packaged versions of games, as is possible with every version of the PSP hardware but the Go. What they don't like is paying an $80 premium for the privilege of being limited only to digital releases.
We admit, we haven't commissioned as much research into consumer behavior as Sony has -- but we think we have a handle on this particular phenomenon.
