To each their own...got a 10.5” iPad Pro in June, have used it to write clinical papers for journals (with reference management and all), study on it daily, get all my communications done, the occasional spreadsheet work, and presentation creation via Keynote and powerpoint, all with no struggle and tremendously liberating versus using my laptop. Meanwhile, my 2013 macbook air hasn’t been booted up in 2 months.
Like i said, to each their own. what you might consider “getting work done” properly on a device suitable to those tasks is very different from someone’s else’s productivity. Using iOS 11 on the Pro feels far less weighed down than the old paradigm of computing for me.
