As I watched Apple\u2019s big unveiling of its new iPhones, Apple Pay, and Watch on Tuesday, I just had to start writing up an "endangered" list. My relationship with the following apps, devices and other stuff could come to an end once I get my hands on an iPhone 6 Plus and Watch. However, there is one gadget that no iOS device will likely topple in terms of my affections.\n\n\n1. iPad mini.\u00a0My friends joke that I have more tablets than a medicine cabinet. And for a while, the iPad mini was my favorite. It seemed the ideal "take-anywhere" tablet. But I\u2019m already planning to sell my mini to help finance my iPhone 6 Plus purchase. The mini just seems unnecessary, caught between the 5.5-inch iPhone 6 Plus "phablet" and my 9.7-inch iPad Air.\n\n\n\n2. Mio Alpha heart rate watch.\u00a0Not long ago, a Starbucks barista I\u2019m friendly with noticed I was wearing two "watches": a Mio Alpha heart rate monitor and a Fitbit Force. \u201cLooks like one watch too many,\u201d he said.\n\n\nI\u2019m thrilled at the prospect of slimming down to a single watch during exercise. It remains to be seen how well the Apple Watch\u2019s heart rate monitor works, of course. But if it\u2019s as effective as the Mio Alpha in continuously recording my heart rate during a workout, I\u2019m kissing the Mio goodbye. My\u00a0Fitbit Force watchband recently, and irreparably, broke, so we\u2019ve already parted ways.\n\n\n3. A Fitbit wearable device.\u00a0In lieu of the Force, I\u2019m now using a Fitbit Flex wristband. Will I still wear the Flex in addition to an Apple Watch when the latter may do everything a Flex does and more? Probably not.\n\n\nOf course, I might. Over the past two years as a loyal Fitbit user, I\u2019ve convinced half a dozen close friends to buy one. We can view each other\u2019s daily step totals in the Fitbit app\u2019s leaderboard \u2014 which is an incredible motivator. I\u2019ll really miss the competition when I switch to an Apple Watch, and I seriously doubt all my friends will opt to follow me there. Even if they did, will we be able to see each other\u2019s step totals, as we can with Fitbit? So far, I\u2019ve not read anything about a similar leaderboard feature with the Apple Watch and its Activity and Workout apps.\n\n\n\n4. A fat wallet.\u00a0My wallet bulges with too many cards. With the new Apple Pay digital payment system, which lets you pay for merchandise using an iPhone 6 or Watch and your linked credit cards, I could start carrying a much slimmer wallet. Good thing, too, because I\u2019ll be devoting a lot of pocket space to that big iPhone.\n\n\n5. Most third-party camera apps.\u00a0Apple\u2019s upcoming iOS 8 (due Sept. 17), coupled with the iPhone 6\u2019s camera improvements, could make me less dependent on some third-party photo apps. Example: I\u2019ve used the GorillaCam iOS app a lot for its rapid-fire burst and time-lapse modes \u2014 two features that are built-in to Apple\u2019s Camera app in iOS 8. (Burst mode is already available on the iPhone 5s, but older devices will get it with iOS 8.) The iOS 8 Photos app also delivers some image enhancement tools that were previously available only in third-party apps.\n\n\nOne Thing That\u2019s Safe \u2014 For Now.\u00a0Though I suspect the iPhone 6 Plus will make an ideal e-reader in many situations, I\u2019m hanging onto my Kindle Paperwhite. Its screen is much more legible in bright sunlight than any iPhone or iPad screen, making the Paperwhite ideal for afternoons in the park or at the beach.
