Apple is intentionally hampering the desktop experience on the iPad and is very late in brining Stage Manager to the iPhone (the rumor is now iOS 19). Until there is serious competition (this and/or improvements to DeX, Apple will drag their feet because they want to sell you three compute device categories (or four if you count the Vision Pro).
Also, stage manager is not a good way of doing real work. It's with good reason that people abhor it on the Mac. On an iPad with no better alternative it's workable but not great.
So true! I have experimented with plugging an iPad Pro into an Apple 7K Studio Monitor with keyboard and an Apple Trackpad and Stage Manager: close to being generally useful, but I also get the idea that Apple is purposely holding back to prevent reducing Mac sales.
That is why I am rooting for Samsung DeX and what Google is offering: Samsung and Google can make money for their own reasons making a universal personal digital device.
