So the simplest way for Apple to get a ARM-based computer would be allowing the iPad to be more of a computer. Alternatively, they do it the hard way and launch ARM-based Macbooks. That would be nice too. But putting iPadOS onto a Macbook would rather go in the wrong direction. MacOS should run well on ARMs anyway.
A nice proof of concept, but I don’t think it’s the right path for a serious tool.
Personally, I would refresh my iPad much more often, without the limitations. And it is not very realistic from Apple to expect people to carry both a laptop and a tablet. So forcing the customers to choose between those device types is not very customer friendly.
Actually, I am currently considering to get the Samsung Galaxy Book S, which seems to be a very interesting, ARM-powered laptop. Of course I would prefer a new iPad Pro, if not for its limitations.
