As well as faster hardware and a better camera, the new iPhone 3GS has a surprise feature that totally sells it for me: an oleophobic coating that makes the screen resistant to face oil and fingerprints.
“The display also features an oil-resistant coating that keeps the iPhone screen clean,” says Apple on a new iPhone 3GS technology webpage.
Oleophobic coatings are used in some sunglasses, making them resistant to greasy fingers, oily faces and dust.
A Japanese iPhone accessory maker, New Sharp Image, offers an oil-reistant screen protector for the iPhone and other devices.
