Apple Pay, the new payment system that uses iPhone 6 together with Touch ID in stores, will debut Monday. This could be a revolution in the way we buy things, and could replace the insecure "swipe and sign" method we use now with credit cards.
iOS 8.1 also will be available tomorrow, but Leo maintains that there's no hurry to download OS updates. It's a good idea to wait a few days to see what ends up getting broken in the new release. If there is something broken, wait a few more days until a fix comes out.
Meanwhile, Google also announced a new version of Android called "Lollipop." The more recent phones such as the Nexus 6 and Galaxy Note 4 will have it, but again, no need to download it immediately.
