That article is pretty much bullshit. It's written by somoene that worked for Apple for starters and most of the conclusions it draws are wrong. I have a Cintiq Companion so let me provide some counter points:
- - Cintiq Companions require no chords. You have a AC adapter to charge the 4+ hour battery and that's it. For desktop displays like the 24HD, you have a power chord and a display connector. I'm not sure why 1 or 2 chords is such a nightmare to handle for the author. You can hookup the second gen companion to your desktop and use it as a drwaing tablet only, but this is a hudge benefit and something the iPad Pro also lacks.
- - Latency is not an issue on my Cintiq Companion and is largely determined by computer hardware and software in my experience.
- - I like the thicker design of the Wacom stylus; it doesn't feel cheap or wobbly. I also like the buttons which are extremely useful to people that work with a stylus every day. There's also an eraser on the reverse side, something Apple's design team failed to figure out. Never having to charge it is also a plus.
- - Cintiq's are heavy but that's because they are well built laptops, not gimmicky tablets. I rountinely take my Cintiq Companion on trips. There are issues with the location of the power button on the first generation companion, but the author hasn't used a Cintiq long enough to know that.
- - There is nothing wrong with the Cintiq Companion's display (minus the air gap, see following point). Older Cintiq displays suffered from poor colours but that is hasn't been the case for a few years now.
- - The only issue she is correct on is the parallax air gap problems with Cintiq monitors. I do wish they would improve this.
My take away from this: Don't get rid of your Wacom just yet. iPad Pro is not a professional tool and doesn't stand up well to a similarly priced Surface Pro or the more expensive and industry leading Wacom line of products.
