ipads have a non-insignificant footprint as point of sales systems these days too, so I wouldn't say ipads are _only_ a consumption device. They are also a pretty solid task specific unit for certain specific industries.
Software developers continuing, after all these years, to dismiss any kind of creative work with a computer that isn’t typing, is crazy. I’d take an iPad over a laptop or desktop computer for lots of creative work, if I could only have one device.
