Apple introduces new iPads, iMacs, launches new OS and Apple Pay

"It's been tremendously busy already, but we have a few more things to show you to close out the year," chief executive Tim Cook teased at the beginning of the event.
Apple Pay, the company's new mobile payments system will debut on Monday. Apple has signed up 500 banks and many more retailers to support Apple Pay, Cook said.
The system uses a near-field communication (NFC) chip that lets users pay with their smartphones instead of credit cards. A feature called Touch ID, which lets users pay for items and apps using a single touch on the fingerprint sensor, also works with Apple Pay.
The company also released its latest desktop operating system, OS X Yosemite, Thursday as a free upgrade. The operating system has added features like better search and notification functions and an improved Safari browser, Apple said. Yosemite allows users to make and receive iPhone calls or texts from their Mac.
Apple's new iPad Mini 3 and iPad Air 2 now include the Touch ID fingerprint sensor which was only available in last year's iPhone 5S and in the new iPhone 6 and 6 Plus. It allows users to unlock their devices and purchase items in iTunes with the touch of a finger.
The devices look similar to the previous models and feature upgraded cameras. Both come in new colors: gold, silver and space grey. Cook aired a video emphasizing the thinness of the new iPad Air 2, which is 6.1 millimetres, or about 18 per cent thinner than the current model.
The gadget is the "world's thinnest tablet," according to Apple's senior vice president of worldwide marketing.
It comes with a new and faster A8X processor, while the iPad Mini is still powered with the A7 chip.
The iPad Mini 3 starts at 399 dollars while the iPad Air 2 has a starting price of 499 dollars.
