The 6.1-inch iPhone 15 and 6.7-inch iPhone 15 Plus can be summed up very easily: recycled parts. Apple's newest non-pro iPhones are made with more environmentally friendly materials and have key features that were first introduced on last year's iPhone 14 Pro and 14 Pro Max.

From a "pro" iPhone perspective, even with features taken from the iPhone 14 Pros, such as the Dynamic Island, a 48-megapixel main camera, and the A16 Bionic chip, the iPhone 15 and 15 Plus aren't quite “pro.”

The new colors are not as vibrant as on past non-pro iPhones and the aluminum is not as premium as titanium on the iPhone 15 Pro and 15 Pro Max. There's no 120Hz "ProMotion"; no always-on display; there's no optical zoom. There's also no customizable Action button.

The difference in features would suggest the iPhone 15 (starting at $799) and 15 Plus (starting at $899) are just watered-down iPhone 14 Pros. And to a certain degree, they kind of are. But it doesn't matter because the iPhone 15 and 15 Plus aren't for the diehard Apple fan or early technology adopter. They're for the person upgrading from an aging iPhone; the Android user who is ready to be a blue bubble; the kid who got mom or dad's hand-me-down phone.

A nameless mesa in a strange Martian landscape once stood at the center of a swirl of alien conspiracy theories.

In a low-resolution snapshot from NASA’s Viking 1 spacecraft, taken in 1976, the brightly lit ridges and darkly shadowed dips in the terrain atop the mesa formed a weirdly compelling optical illusion: a grim, black-eyed face staring back at us from Mars. Conspiracy theorists insisted the mesa must have been the work of alien sculptors. But it turns out that if you see the mesa in more detail and in different lighting, the stark contrasts of light and shadow that originally formed the face completely disappear.

But the “face on Mars” is a great example of the same phenomenon that may once have inspired early humans to draw some of the first art on cave walls here on Earth.
