Big Apple
"The Big Apple" was popularized as a name for New York City by John J. Fitz Gerald in a number of horse-racing articles for the "New York Morning Telegraph" in the 1920s. The earliest of these was a casual reference on 3rd May, 1921:
Apple Pippin
The Apple Pippin platform was named for the Newtown Pippin, an apple cultivar, a smaller and more tart relative of the McIntosh apple (which is the namesake of the Macintosh). According to Apple, it intended for Pippin to be more than just a platform for game consoles. "Apple believes that over time Pippin will take many forms, including home telecommunication devices and much more. Apple did not want to choose a name that would be specific for a certain market space, as it will certainly appeal to many types of consumers and be shipped in a variety of forms from many manufacturers."
