It wouldn’t surprise me if some readers might have been perplexed that my first post after the iPhone Duo announcement was a faux 2018 review of iPad multitasking from an alternative universe. While maybe it was a little self-indulgent (I did have fun writing it), the Duo does feel like an iPad from an alternative universe to me. What struck me in particular and what inspired the faux review was just how utterly intuitive Split View multitasking looks on the Duo.
Apple’s greatest designs elicit an “oh, duh, of course” when revealed. They’re not just good, they’re right. What distinguishes the “right” from the “good” is that the former has a sort of singular-ness. In a given problem space, good designs coexist and compete with other good designs, while the right designs end up standing alone because they are so obvious that any alternatives inevitably, if not immediately, seem backward. A good example of Apple defining the right design is the keyboard and trackball layout of the original PowerBook series. Unlike early PC laptops that had keyboards shifted forward toward their front edge, the PowerBook’s keyboard was shifted back towards the display, which naturally created room for a trackball and palm rests. Because the PowerBook’s layout was the right design, all laptops eventually shifted their keyboard’s back towards the display.
A more recent example of Apple defining the right design is the Home Indicator, which replaced the Home Button starting with the iPhone X. The Home Indicator was also utterly intuitive, even at launch. Swiping up to go home was immediately obvious and other gestures were easily discoverable. My employer recently bought me an Android phone to test with. Like a modern iPhone, its screen goes edge-to-edge and, because the Home Indicator was the right design, this Android phone has what is basically a Home Indicator.
Despite all the incredible engineering that went into making Apple’s first folding phone, the Duo’s most “oh, duh, of course” moment for me was the exceedingly simple and obvious-in-hindsight idea of basically treating each half of the screen as two instances of the same iPhone, each with their Home Indicator. Had the Duo been Apple’s first device that supported Split View on iOS, the “oh, duh, of course” of this design would have been sheer delight. What makes it bittersweet and what inspired my faux review is that Apple has been offering some form of Split View on iPads for 11 years now and it’s always been clunky. Per my review, that was somewhat forgivable when it only ran on iPads with Home Buttons, but it remained clunky even after iPads switched to Home Indicators. Split View was revised in 2021 with iPadOS 15 and it was still clunky. A window manager was added iPadOS just last year and, you know what, Split View is still clunky.
The implication in my faux review was that multitasking on iPads was doomed the moment Apple decided to launch it on hardware that was still locked to a single-app paradigm via a Home Button. I think the Duo is evidence of that. Not being an iPad meant those working on the Duo could look at Split View with fresh eyes, which seemingly led them to the right design1, one that ironically should have been on the iPad almost a decade ago.
- The two Home Indicator approach seemed so obvious in hindsight to me that I had to check if Android already implemented something similar. Unsurprisingly, Android seems to have copied what Apple introduced in iPadOS 15. As a fan of Apple, seeing competitors blindly copy the company’s design is always amusing, which becomes hilarious when the design they’re copying isn’t even that good to begin with. To that end, I fully expect Android to copy the Duo’s approach by this time next year. ↩
