Will your choice of phablet determine the mobile ecosystem you get locked into for health and fitness tracking, automobile navigation and home entertainment?\nI\u2019ve been mulling this questions since I saw Google\u2019s flurry of news at its 2014 I\/O conference this week. More on that in a second. First, let\u2019s start with Apple, which is expected to release two big-screened iPhone 6 phones this fall, one model at 4.7 inches and another at 5.5 inches.\nApple\u2019s current iPhone 5 models max out at 4 inches and can\u2019t compare to Samsung\u2019s army of phablets, including the Samsung Galaxy Note 3 (5.7-inch screen) and the Galaxy Mega (6.3 inches). But will supersized Apple phones lure phablet fans away from their Samsungs?\nI doubt we'll see a mass exodus, becasue there are many happy Samsung phablet users out there. Still, a few trends are worth noting:\n\nThe appetite for phablets appears to be growing in general. The phablet share of smartphone shipments went from 4.3 percent in early 2013 to 10.5 percent one year later, according to IDC,\u00a0a CIO.com\u00a0sibling company.\u00a0\u00a0\u00a0 \u00a0\nInterest in the iPhone 6 is high. Fifty percent of consumers planning a phone upgrade in the next three months say they\u2019ll get an iPhone, and 25 percent say they\u2019re willing to spend $100 more to get one with a 5.5-inch screen, according to a new RBC Capital Markets report.\u00a0\u00a0\n\nThis could mean there will be a fair amount of Android-to-iOS switchers this fall. Moving from Android to iOS or vice versa may not seem like a huge deal \u2014 until you consider the future of both platforms.\nRecent announcements from Apple (at its WWDC developer conference) and Google (at I\/O) clearly illustrate that their mobile ecosystems are poised to expand far beyond smartphones and tablets in the near future.\nBoth Apple and Google are busy integrating health and fitness apps, APIs and smartwatch\/fitness trackers into their respective ecosystems. Both are vying to become your car\u2019s mobile OS. Android TV is coming to a set-top box near you later this year to compete against, among others, Apple TV, as well as the physical Apple television the company is said to be building. Don\u2019t even get me started on the "Internet of Things," as part of which refrigerators, toaster ovens, crockpots and other everyday appliances will no doubt soon be hooked into and controlled by apps within the Android and iOS ecosystems. The goal of both companies is to deeply interconnect the various devices on their platforms so that, for instance, you can control your TV set with your smartwatch.\u00a0\nAs the months and years tick by, the Apple and Google platforms will undoubtedly invade many areas of our lives. Of course, it\u2019s quite possible to live with one foot planted in each ecosystem. I do. But the benefits of mobile OS agnosticism will likely reach diminishing returns over time, forcing most people into one camp or the other.\nSo if you find yourself mulling a jump from Android to iOS or the other way around, choose carefully. Whichever road you take, the further you go, the harder it will be to turn back.
