I'd say this rather shows how your judging of character works.
I thought you were pulling my leg so I pulled yours. I've not argued the need to take a MacBook Pro and a Surface Book have I? Are you saying the reason why you take a Surface Book in your bag all the time along with an iPad and a MacBook Pro its because the Macbook Pro lacks touch?
I've used Surfaces for 2 years for work exclusively. It is not really efficient. Meanwhile it cost $3000. You see, when I'm having a meal the most effective way to tackle the this task is to have a fork and a knife available at the same time. Not one + half of another, one at a time. I understand that there might be scenarios were as solution such as the one pictured is what is needed but for that matter I already have a smartphone. Hope this analogy its ok. Don’t get fogged by Cuteness and Marketing.
In essence having an iPad Pro and a MacBook Pro its like having a Surface Book but better. Instead jump out of the office desk, detach the screen interrupting whatever background processes, and go to a meeting. I simply pick my iPad Pro, and go to the meeting, the screen its already detached and all my information is in sync. Instead of turning the entire laptop around to take notes with a pen, interrupting my coding flow, I can keep on coding in the laptop and take notes with a pen on iPad Pro all the the same time.
This is the kind of stuff I would like to see Apple move forward. The connection between the "cutlery", handoff in real-time and not focus on making this:
The example in the image is what the Surface line is all about. Cute but I don't want it, been there, done that, it does not work well. They sell the above has the Pro tool, well Pro's 98% of the time don't need that. I'm sure there is a space for the above, we already have an offer in the market for it.
Currently I don't use desktops. I decided a decade ago to move to laptops, I need to be able to do deep work anywhere. To do it, needed leave behind the performance of desktops. But I see an opportunity with the iPad Pro to get that performance back without leaving anything behind. At the moment I cannot as described above.
For intensive in a non handheld position, computer on a desk, there is nothing better than a mouse and a keyboard. If Apple fights against this, a Xerox Parc solution that SJ every so often talked about, they will loose because it’s a very good solution for the desk desk context. I understand that iOS is a Handheld OS armed with a strong ecosystem of productivity and creativity tools. All its needed is a mouse and a keyboard for mobile situations for a perfect cutlery. Don't see how such support would compromise the Handheld abilities.
If they do support it I can easily see myself leaving the desktop at the office connect to it via Back to My Mac when needed with my iPad Pro 12.5 inch and start coding. For regular office tasks the iPad Pro is already there for the most part, except for the lack of mouse support for the situations above. No need for Back to Mt Mac for that.
I know Ii'm repeating myself, but for me at the moment it all comes down to this. For Photography and Video editing when out and about its also very much there as creatives admit.
Apple with all the vote of confidence the customers gave them, with all the money they have, they have the moral obligation to move faster with their Handheld OS. The risk is having another company delaying progress for another 10 years or more in the field with their product above, capturing the minds of smart people like you because Apple has not done the job properly. iOS 13 should be here already (I think is when they plan to make another functional leap with it).
MS with Windows 10 did everything the users asked for, everything. And its a mess with users even the fans still complaining ...
Apple with OSX did everything they thought the best, and its a lean mean OS, so is iOS.
Cheers.
