What a simple and brilliant idea for those of us that obsess endlessly about things rather than going to the store and trying to guess what size they are ;-)

I quickly entered the Zen Vision M (which I currently have) and compared against the INsignia DV4G (which I’m considering getting instead):

You can see the actual comparison on the site here and view comparisons from other perspectives as well.

It’s super easy to enter sizes in inches or mm and insert common objects like the deck of cards and matches you see in the picture. A future integration idea might be a way to upload a picture of your item(s) into at least one of the perspectives just to make it that much more real feeling.
