世論 What Japan Thinks

With almost all new cellphones now having a memory card slot with media costs dropping drastically, and listening to music on phones becoming more popular, here’s an interesting survey reported on by japan.internet.com and conducted by JR Tokai Express Research Inc into the topic of cellphone memory card usage.

Demographics

On the 13th of February 2008 330 members of the JR Tokai Express Research online monitor group employed in either the private or public sector completed a private internet-based questionnaire. 83.9% of the sample was male, 10.9% in their twenties, 38.5% in their thirties, 39.4% in their forties, 8.8% in their fifties, and 2.4% in their sixties.

A year and a half ago (summer 2006) a similar question was asked, and at that time 128 MB was the most popular size, so that’s a quite impressive factor of 8 larger.
