This shot is the companion to: Sub-pixel text rendering
The attachment can be used to compare sub-pixel antialiased text and standard antialiased text on an iPhone, if you'd like to see if you can tell the difference (iOS doesn't render sub-pixel antialiased text).
To use the image, you'll have to display it at precisely 100% with the home button icon next to the home button on the iPhone.
The text blocks were created in TextEdit on a Mac. The standard antialiased text is a greyscale version of the sub-pixel antialiased text, to ensure there's no difference in font weight.
