As far as user interfaces are involved, unifying the desktop and mobile environment is simply stupid. I'm not using my CAD the same way I'm fiddling with my tablet, get over it once and for all.Head of departments may disagree, but that's because they know jack$#!& about drawing with CAD software for hours on. Try doing that on a mobile touchscreen device, you monkey.
And this is true for a hundred other professional softwares.
I don't disagree that, on your end, you wouldn't want to work CAD all day on a tablet, but perhaps you don't see the bounty it might provide for production. I'm building a comprehensive report that shows use of mobile tech, travelling along with the object (right now it's practically a ream of paperwork) opens up feasibility and communication. Perhaps there's an error in the print? Instead of going to the supervisor, the supervisor calling the engineer, the engineer having to be available, answer the question back downhill to production, a simple real-time message could be sent, the digital print annotated and revised at a later point when the engineer's available at a desktop environment.
As far as homogenizing operating systems, I don't see it too far off simply because we all use the same hardware anyway. Obviously Microsoft thinks they're going to be king of that hill, and I think that's where they're clueless. Apple and Microsoft are literally in operating systems to dumb down computer use for the least capable to do so. The complexity of what computers do, however, is steadily increasing, requiring something more like Linux, where the OS can be modded to support specific operations, appearance, etc.
I do have a tablet, with a couple of CAD apps, which I do use to make annotations, corrections and updates "on the field" (naval engineering).
Do I appreciate the sheer usefulness of the whole thing? Sure I do.
Do I like the CAD interface (precision, usability, responsiveness, etc.)? Nope.
Do I think the two things should look the same on the two very different environments (desktop with keyboard and mouse vs tablet with touchscreen)? Nope, again.
Is the tablet apt to be used for prolonged typing (as in writing lines of code, or just detailed reports), or digital drawing with layers, filters, effects, and a hundred other professional kinds of work? Nope, for the third time.
An handheld, portable device such as a touchscreen tablet is really usful for minor corrections, small and absolutely not complex updates, or even generic sketching a layout of a new work. But it's close to useless for detailed, in depth or long term working (don't get me started on batteries duration).
It's a cool gadget to keep up to date various small thingies, and that's it. End of the line. I need a different tool, with a different environment and user interface to get my job done properly. Having a full options range on the tablet would clutter it to oblivion, while streamlining the one on the desktop (ribbon interface instead of toolbars has already been a nasty step in that direction) would take away the true power of the software at hand.
A single, unified user interface is ANTTDNW (another nice trick that does not work), at least with the current technology.
