With that rant out of the way, though, the poll (in which 401 mobile phone users partook) shows that 42% of Japanese men prefer the PSP, while 30.3% prefer the DS Lite and 16.8% the Phat. As for women, 52.2% picked the Lite and 27.4% chose the Phat, while only 8.8% prefered the PSP. (Note: In case you're wondering why these numbers don't add up to 100%, the unlisted percents were split between the Game Boy, Game Boy Advance, and Game Boy Advance SP.)
While we know you can't trust statistics (especially of this nature) and should only take them with a grain of salt, we found this study to be pretty interesting. If these numbers do happen to be indicative of the general population, it would show that Japanese men are pretty split in their handheld preferences, while Japanese women are overwhelmingly in favor of the DS. That would be in line with Nintendo's strategy this generation, as the company has made an extravagant effort to appeal to gamers in every demographic.
