I use Keynote a lot and do mostly pretty complex slides. iOS version is great for presenting and OK for minor edits. For general stuff it's useless.
Router analogy is pointless. iPads are marketed as "Pro", "content creation" and even "PC replacements".

I believe you are wrong about complex presentations. Check out Keynote. I would love to have an advanced time line in Keynote like those in 3D apps but that is not strictly necessary. Custom made shape library is also very useful.
Scientific writing is a software problem (target audience is too small so microsoft has not embedded a good reference manager). If you add that criteria, you can just as well add engineering software etc which also is very limited on MacOS.
Ability to create software is a funny criteria. I believes the software in the router, car, oven etc cannot be created in the router, car or oven.
Who said that the iPad was a replacement for software development, engineering and other very specialised application areas?
