How is iPads are most versatile home computer? Can it connect my my USB drive? Can it connected to my USB printer? Does it have multi-users account? Can you format external disk with iPad? If all you do is just going to browsers and streaming videos, any devices can do. You don’t need waste your money on iPads. I can do thing just fine with $100 dollar Amazon tablet.
At least you can virtualized Windows on a mac or you can bootcamp to Windows on a Mac if you need to run Windows program. Can you do that with iPad?
It's versatile in that the iPad does like 80% of the stuff I want to do on a computer. I still have a PC to deal with the other 20%, and that's my point from the get go. I am not looking for the iPad to replace every single computing device in my house, but it does offer clear advantages over a conventional PC in a number of use cases that are relevant to me, and so for me at least, there is value in splurging on a high-end iPad because when you use the iPad for as many hours a day as I do, even the smallest refinement goes a long way in improving the user experience significantly.
I can also think of a number of differences between an iPad and a $100 amazon tablet. For one, apps. The mobile web sucks. Even using reddit in desktop safari feels like a chore. On my iPad, I have Apollo for browsing reddit, Tweetbot for twitter, Tapatalk for Macrumours (though the app seems to have gotten buggier of late), Machash for all my Mac-related news, Reeder for everything else (though there is admittedly some overlap with Twitter), Overcast and Marvis for audio listening, safari for everything else (and even that is with a number of ad blockers and extensions).
I don't have multiple user accounts on my MBA either. I can print wirelessly from my iPad and yes, ipad pros can now access usb drives via its charging port (though you will need an adaptor for usb-A drives but I have Samsung T5 drives for that, and it's no different for M1 MBA). I can't remember the last time I had to format an external drive, nor have I had to bootcamp into windows. And in the rare occasion that I need to, well, my MBA and my iMac are just a short distance away.
If I had to travel overseas with my students again, I am comfortable bringing only my iPad, while leaving my laptop at home, because again, the iPad does what it need it to do in this specific context, and boasts a number of advantages over the laptop (longer battery life, ability to detach the keyboard, cellular connectivity).
It's like having a toolbox. I don't have this one magical widget that magically morphs into any tool that I want at any one time. Instead, I have a variety of tools, each with a specific use case for a specific purpose. I have a smartphone, a tablet, 2 laptops (one from work, one personal), an iMac (that I share with my dad), Apple TVs, a Nintendo switch (that I rarely use), Apple Watch and AirPods.
I don't need one device that can magically do them all, and I am willing to bet that even if there were such a product, having the best of all worlds likely means having to deal with the worst of all worlds as well.
The more I think about it, the more I find that the benefit of the iPad over the PC is accessibility and ease of use. I can't get all my work done solely from an iPad, but I appreciate that the iPad is different enough from a conventional computer that it affords me a unique user experience.
And I believe this is due to the iPad running iOS. For me at least, the iPad being a glorified blown-up iPod touch is a feature, not a bug.
