At its launch back in 2010, the iPad was heavily criticized for being a big iPhone. iOS 11 and the iPad Pro proved that wasn’t the case. Things further diverged with the introduction of the iPhone X, which has led to some confusion for anyone who regularly uses an iPad. I’ve been using an iPhone X and iPad Pro together for nearly six months now, and I often feel lost when moving back and forth between the devices — one with a physical home button, the other with webOS-like gestures. The result is a vastly different user experience, even though they run the same version of iOS on large rectangles of glass.

Now, Apple is rumored to be ditching the home button on the iPad Pro in favor of Face ID. It’s a move that makes sense, and it will present Apple with an opportunity to more closely align its tablet with the iPhone X gestures or to further differentiate the iPad as an entirely different computing platform (one that’s wholly separate from the iPhone, in the same way that the iPhone is distinct from the Mac, Apple TV, and Apple Watch). Either way, Apple is facing an iPad gesture dilemma.
