As I said above, it looks exactly like a MS Surface, but doesn't come with a keyboard.
Instead you need to buy it separately for 160US.
However it (Smart Keyboard) is the same kind of low profile keyboard (but lacks the touchpad that the Surface has.)
It works with a pencil (99US) which also may need to be purchased separately.
I do not see any USB connectors for mouse, but all models have Bluetooth 4.2.
They are 10.5" and 12.9", so as big (or nearly) as some MacBooks.
I am not a "Mac person" (and never will be.) I'm not advocating,... just being understanding.
This thread (and feature request) is not at all about "the already available answer".
And, being a Windows geek since Windows 1.0 (and before that the original 4.77 MHz IBM PC with PC-DOS.. remember this days?) ... yes, I'd choose a Surface (if I thought they were worth the money, but I don't. I would buy some other touchscreen detachable notebook instead.)
But this thread isn't really about my choice of Windows platforms. It's about whether Trimble should translate their code to iOS, and if so, how would it be deployed.
Since it (the iPad Pro edition) has an optional keyboard, and I know people who prefer pen-like pointing devices (I remember even I used a cheap pen mouse with AutoCAD back in the mid-90s till I wore the button switches out.)
So I can understand why Mac lovers would want a portable SketchUp edition for the iPad Pro.
But, understanding the Mac end user's point of view, doesn't mean I advocate that Trimble should do this "just to keep up".
In fact, as a policy, they've never tried to "keep up" with AutoDesk or even any of AutoDesk's individual products. SketchUp has been called "the UNCAD". The workflow, the keyboard shortcut system, etc., was purposefully designed to be different than that of the traditional CAD products. This is part of SketchUp's design philosophy.
Anyway, ... if the number of iPad Pro owners out of the total number of SketchUp licensees gets to a point where it economically makes sense, then they could implement an iOS edition.
But "economically" means that the cost is paid for down the road somehow. Firstly it should not be too expensive, to translate the core Objective-C or the my.sketchup code to iOS code. (I'd think the latter would be quicker and simpler.)
If the cost is offset by desktop SketchUp Pro licenses (even if it's given free to Pro licensees,) and this helps increase licensee sales, and therefore encourages the application support,... I'd not complain (even though I'd not personally benefit.)
But I am not in favor of just implementing this free for all, just to "keep up". I've seen a multitude of companies and CAD clones who tried this, disappear from existence.
If it is economically feasible for a paid iOS app for anyone, (regardless of desktop licensee,) and these sales offset enough of the development cost, then again I'd not complain either. (Perhaps this route of a paid app can give desktop licensees a discount, ie the 2 licenses are "bundled" into one price?)
