Keeping with the theme of this week, we're introducing another new feature called "Size Matters." Thanks to sar7501 for the name idea...it works on so many levels.

Anyway, "Size Matters" compares the sizes of products to other similar products and everyday items. You'll see that here at TechJapan we report on product dimensions for nearly every article; for mobile devices/handheld in particular, size really does matter.

So, to kick things off, we've got some actual size images of the Nintendo DS and PSP, and will be comparing the size of each device to a DVD.
