Perhaps not lifting trucks or any serious computing, but it clearly has her typing on a keyboard in laptop mode and later using the Pencil in tablet mode. Power is one issue, but you can’t deny it’s convenience factor.
Sure, I get there are needs that require a horsepower for computational work. But similarly there are many professionals who truly don’t need anything more powerful than the 13” entry-level MBP. Heck, even the 10.5” iPad Pro w/A10x chip, is more than enough and weighs all of 1lbs. A fully integrated keyboard won’t add much to that.
It’s not about Apple following what other manufacturers have done. Perhaps I’m just questioning Apple’s philosophy. Yes, they’ve maintained that independant devices is their vision.
But with rumours of iOS and MacOS merging, iPad’s positioned as a computer, and A-series chips performance, I can see a future where 2 become 1.
Of course many professionals do not need the horsepower of a high end CPU, the term professional is very vague in that anyone who makes a living from something.
However what I mean is by incorporating both devices, you end up with a reduced performance device for the same cost. I am sure they could do it all and make it powerful, but the entry level would be $2500, with the performance entry at closer to $4000. Which is a lot. Basically, you're moving the baseline up the price scale, which would mean lower end users paying more for less, and higher end users paying a lot more for stuff they don't need/want. Which would surely affect their customer base.
Personally, I will always prefer separate dedicated devices, that are optimised for their purpose. Rather than having to compromise for little benefit. As I said earlier they are great for enthusiast audiences, someone who wants a reasonable computer with these functions and doesn't want to pay a small fortune for it. But I'd rather have a high end laptop to do my work, with a high end tablet to do other stuff. And on the cost, just take a Cintiq HD and strap a MBP to it, you're essentially adding at least $1500 for the luxury.
As to other points. iOS and MacOS are built on the same kernel, they are the same OS but are developed differently for their use cases. A touchscreen interface is no benefit with a mouse input, and there's not enough real-estate on a phone to make use of a mouse. You basically end up with Windows 10, which love or hate it, Microsoft have and do invest a lot of R&D/Finances into making it work, and personally it doesn't work. So it's really not an easy task.
iPad's are computers, just as an iPhone is or even a smart-watch, just because it doesn't have a mouse and keyboard does not make it a computer. You can do a lot with an iPad which make them a great alternative if you don't need a full sized computer (Which increasingly is becoming less of a need). If you're just doing emails and web browsing, then they are great. If you are editing photos, light sketching, or even light music production, then again they are pretty good. If you are trying to model a 3D scene, adjust architectural drawings, or anything else high end, then they do not have the software or the user experience to make this productive.
SoC's have great performance in benchmarks, but real-world performance cannot match a dedicated CPU/RAM/GPU combination. Again maybe one day this will change, but I wouldn't hold my breath for at least another 10 years. They're a different class of CPU, one designed for less intensive tasks where efficiency and energy conservation is desired over performance and sustainability of power. There's also architecture and software emulation to take account of, but that is something that could/would happen if needed.
As I said the lower end tasks are increasingly available on more portable devices, which do not require massive performance peaks afforded by high end i7's. So it's great to offer things such as portability and longer battery life in sacrificing performance for those who don't need it. So I think we'll see more investment into things like this, with some experimentation in this area (Like the newer SoC Windows systems offering 20 hours battery life), but in all honesty it's probably just the latest fad to sell computers, 10 years ago it was the ultra portable Netbooks, 5 years ago it was the touchscreens, today it's the long battery life. Same for any technology industry really, 10 years ago TV's were all about 3D, 5 years ago all about being curved, today all about 4K HDR... They need to do something to make you want to upgrade your stuff!
So for what it's worth, I'd love to see Apple try a Surface Book style device, I think they're great and have potential. But as a consumer product in Apple's lineup, I don't see it working. The ability to have the best of both is a good one, but they'd need to hugely increase the battery life and hardware to make it work (Which as I said would push the price up too much), and then it'd need an overhaul of the interface. Maybe it'll happen one day, they probably already have several prototypes lying around after all.
