Sizeasy Beta
Have trouble visualizing just how big or small something really is, particularly when comparing things like PDA's? Sizeasy allows you to add items and compare the size to something else, like a pack of matches or deck of playing cards.
For instance, I compared the size of the Apple iPhone, the HTC Kaiser, a deck of cards, a credit card, and the Treo 750, and below was the size comparison:
There's a 3D view, top view, side view, and front view. For those who have been saying 6 inches is really 8 inches, this is your tool.
