Why we settled on 19x19 is another question compared to why we use uneven board sizes. Anyway, people a really good in making up convincing reasons for some arbitrarily decisions. But this proves nothing (just look into split-brain research). I found the research of http://www.youtube.com/embed/JMDjpSQUH74. According to him 19x19 is just much nearer to the number of days in a year than 17x17. Therefore a board of this size is more useful as a calendar.
