Made famous by this picture comparing the size of an iPhone to other devices, Sizeasy helps you visualize how big something is by comparing it to other things. As in the iPhone example, it's especially useful for consumer electronics, where a centimeter can make a big difference in comfort and usability that isn't obvious from the numbers alone. I'm always surprised by how small cameras and MP3 players are when I see them in person, because I spend a lot of time looking at context-less photos of them before encountering them.

Here's three digital cameras and a soda can, which I put together because I can't find a Canon PowerShot G7 in a store to try out. The PowerShot SD700 is widely available (and damn is it small!), and the Olympus C3030 is my current camera.

Note to sizeasy development team: Please implement a way to rotate an item in the view, including the presets. Thanks!
