I don’t think your comparison makes sense. If someone is buying an iPad to make it them main computer, it’s because they need iPad features (note taking, drawing, etc).
A 256gb iPad Air+ Logitech keyboard is $900. It’s cheaper than buying a MacBook Air+ iPad ($1300).
You maybe right but I was comparing Apples to Apples in terms of acessories. So, I was looking at the Magic Keyboard, which is a lot more expensive. Also, there are lots of deals for the MBA at $900, and I suspect for the standard iPad soon. They just make more of the standard iPad so big box stores are frequently discounting them down to $250.
It all depends on what you want. Like I said, “for my purposes”, so YMMV.
