Ipads are great devices, there is no argument here. However, they are not PCs, and can replace a PC only for the most basic tasks (e.g., reading and browsing) because of the crippled operating system they are paired with. So why does Apple emphasize how powerful the ipad pro is in comparison with a PC? As far as I'm concerned, it can have petaflops of computational power, but unless i could use python, octave and R with it, it would never replace even a 2009 macbook pro. I think Apple should forget this whole "pro" bovine droppings ad strategy, and focus on how great the ipad is as a consumer electronics device. And if they really want to focus on the pro segment, they should come up with a way to run mac os on ipad pro.
What percentage of the computer buying public need to run python, octave or R? Very small. So, there is the answer to your question.
The ugly secret is that most people mainly use their personal computers for content consumption and light productivity (email, calendar, notes, reviewing and editing documents). The iPad is fine for this stuff. Also, most people have a corporate computer provided by their employer for the real heavy lifting. In the old day, we all had desktop towers at home just to browse the web, answer email, store a few family photos, and play an occasional game. Today, you really only need an iPad to do most of the routine personal computing activities.
