iPad Air

We know the iPad Pro will have a display with a diagonal of roughly 12.9 inches, but what about the rest of the device’s dimensions?

Apple showed off thinner iPads and a new iMac with a high-resolution display on Thursday. Sleek and stunning, yes, but not likely to spark the next iRevolution. The tech giant’s bigger strategic bet is that mobile pay service Apple Pay, debuting Monday, will be the next thing you didn’t know you needed — but now can’t live without.

Apple made its new Mac operating system, Yosemite, available as a free download starting Thursday. Apple Pay, the company’s new system for using iPhones to make credit and debit card payments at retail stores, will launch on Monday.
