iPad are the best versions of "tablets", if we see tablets as a frozen in time "large iphone" version of the concept. Android tablets perfectly fit the category and Samsung is the only distant competion (yet Samsung has Dex, which is increasingly showing its teeth)
But they're way behind in term of tablets as touch enabled computers. Chromebooks have seen more adoption as schools and orgs couldn't justify iPad's price, the top of the line is above what the iPad has to offer, and the Surface Pro took the spot of the North Star of the category, to use the article's metaphor.
So yes, I'd agree with parent, Apple could have made the "what is a computer?" marketing campaign a reality, but didn't have the courage to canibalize their mac line.
> Apple isn't a big enterprise player as far as (except for development)
They never really went after the tech companies themselves. The way Macs dominate certain development fields is a result of their popularity with consumers that drove companies to adopt the tech to attract talent. Me and many colleagues 5 years ago weren't interested in web startups using a Windows dev environment. Not saying there's merit to that, but my main point is that Apple focused on the end user(which happened to be a burgeoning web dev class during the last 15 years) rather than enterprise.
I think it's further evidenced by how relatively slow Apple has been to deploy some management tools that are more common in Windows-land. Anecodtally it feels like 3rd parties filled the gap on that side for Apple for quite a while. MDM, other IT tools, repair networks, and more recently self-repair kits were all much slower to deploy than how Microsoft (think Dell) went after their corporate customers.
