I'm not sure why people started thinking this makes it a true laptop replacement.
This has been Apple marketing slogan ever since iOS 9 introduced SplitView/SlideOver, and for some it can be a laptop replacement. It has been a laptop replacement for me, I use a iMac when I’m stationary... but for mobility computing... I use my iPad Pro.
With iOS 10... Apple targeted the iPhone with iMessage features and 3D Touch improvements. But with this new multitask that Apple has introduce in iOS 11... this will fuel the fire even more and I’m sure Apple will market heavily toward the iPad being a laptop replacement.
