I don't think its trajectory needs to change.
For me, personally, the iPad Pro doesn't offer enough to make it a compelling alternative to the Mac. However, clearly people exist who prefer it.
I think Apple has figured out a system by which the Mac and iPadOS can cross-pollinate to some extent, which some people seem to insist means they'll merge in the long run. I don't think so. They just inspire each other.
Now, the pace I'm less happy with. We're eleven years in, so roughly in the equivalent of the System 7.5.x era. At that point, macOS had already grown a ton, and it had some very clear killer apps, such as DTP. I wonder if that's what's missing for the iPad, and I do wonder if, around the time Steve died, there was a decision that they no longer want/need to do excellent first-party apps. (Keep in mind the iPad 2 was introduced with Garage Band. Where's 2021's equivalent of that?) Decent apps like Linea exist, but no must-haves, it seems.
And while I'm happy how much more discoverable they've made multitasking in iPadOS 15, I just can't see how it took the company that brought GUIs to the mainstream about six years to come to the insight of "what if we added a button, and it pops out a menu?".
This is an interesting take.
I think that going forward, things are going to accelerate for the iPad. And I think people underestimate how FAST Apple got their DESKTOP chip onto an iPad. An
iPad, fellas.
All this time, Apple has been working to make the iPad a device powerful enough that can replace a laptop for most people. But they have to start somewhere. That somewhere was Apple Silicon. It took ten years, but now the iPad is something truly viable for the bell curve of total computer users, and the absolute perfect iLife device that Steve Jobs envisioned so long ago.
People forget that Steve was working on the iPad BEFORE iPhone, but the iPhone became the Sun in the Apple Solar System, displacing the Mac.
However, the iPad was the culmination of Steve's "a computer for 'everyone'" vision.
Every year the iPad gets capability added without destroying the existing experience. Yes, it seems like a snail's pace, but now that Apple Silicon is finally desktop worthy (and the iPad was really the test bed to get there) things are going to change faster.
Today, Apple is a little busy not only transitioning the legacy Mac environments to the work that began on the iPad (or iPhone, depending on your perspective), but managing the
consumer ecosystem platforms that integrate said iLife experience (Watch, AirPods, TV). All with the iPhone at its center.
I think once the 2022 date is reached and the AS Mac transition is complete, it's going to get REAL interesting at Apple.
