I don’t take a laptop with me when I travel, because the iPad is more than enough for my work needs for a few days. Working with large spreadsheets is the only thing I absolutely need a computer for.

I have friends who are programmers and regularly work on just an iPad. As I understand it, they only need a computer for some more horsepower-hungry parts of their workflow.

The real problem with iPads is iPadOS. It’s intentionally gimped so you need a computer for some tasks. The iPad Pro has more than enough processing power and memory for full workloads (as well it should, given the price point), the OS is the restricting factor.
