I do wonder though, what is it that causes handhelds to consistently have much lower attach rates than home consoles? I have two hypotheses. The first one is that the average age of handheld players/owners might be lower than the average age of home console players/owners, and less disposable income leads to fewer games being bought (although that is partially made up for by more free time, thus more time disposable for playing games). My other hypothesis is that people are more likely to buy multiple versions of a handheld than a home console, largely because it's cheaper, so it's easier to justify the purchase. I don't really have evidence for this, it's just anecdotal but all the people I know that owns handhelds (or used to own handhelds) owned several of the same handheld (I have a friend that owned 4 different DSs, even though none of them broke).
