This "only a consumption device" thing is just getting so old and dated. It implies that people can not possibly be productive using an iPad, which is just plain absurd.
I have been retired for over a year, but there was a senior manager in our organization that used to carry an iPad around with him to meetings and on travel.....never took a laptop. In his office, he had a desktop. He would use the iPad to reply to emails, calendar, take notes, create/review documents, annotate PDFs, review presentations and spreadsheets. I think he was very productive with the device. When he had heavy lifting to do, he would use the desktop computer.
Now, this guy was my boss....so, maybe I should have set him straight. "Hey boss, you aren't being productive in these meetings and business trips because your using an iPad which is clearly just a consumption device." Of course, his reply might be; "Thanks for pointing that out. I was just marking-up your department's annual salary review on my iPad, and now I know exactly how to handle it."
There are definitely things that a laptop does better than an iPad.....spreadsheets for example. So, if you said something like; "I do a lot of spreadsheet creation and manipulation of large data bases while away from my office computer, so a laptop is really the better device for me." Most folks would totally get it....and you are unlikely to find anyone on this forum advocating for an iPad given that use case.
But, I would not say that an iPad is just a consumption device.
