Take this into consideration... times have changed, and the cool factor of all things nerdy add a certain mystique to a person that never previously had it. Also, as my previous sentence points out, you are able to use the word cool and nerdy in the same sentence.
In an era of skinny jeans, bad hairstyles, too many people thinking they are artistic, and lots of would be musicians, bringing a girl home is enhanced when you have an otaku keyboard.
Why? How do I make this connection? Do you know how amazing it is for a girl who meet a guy with ripped arms who can take her home and discover that secretly the guys is actually into technology that could enhance her skills such as hacking, speed typing, or prevention of tendonitis?
Girls like a man with an edge, and among all the would be nerds with a light up keyboard and glo stix soldered to the side of their unfashionable antec cases, an otaku keyboard fits the bill between sheik, and ravishingly brainy. The ladies love the contrast.
Its true.
Go otaku. You wont regret it.
