A tablet will never replace a computer.
1. Tablets typically have primitive mobile operating systems with a ton of limitations and incompatibilities.
Running desctop software is usually impossible, forcing people to choose stripped-down mobile software.
The exception is Intel-Windows tablets, but they are rare, and good models are relatively expensive but have shorter battery life.
2. Tablets are usually locked down and not designed for work. Although... it depends on what you mean by work. If you're just doing some drawing, maybe.
And productive work involves saving results, backups, software tweaks, and working with networks, normal networks like everyone else.
3. Tablets are weaker than computers in terms of performance, they have limited memory, and they don't have much storage space. However, this isn't a critical point.
4. Tablets don't have enough USB ports, and for this reason are only good as wearables.
What's the point of lugging around a bag of adapters and cables, a keyboard, mouse, and power supply if all this junk is heavier than a laptop and less convenient?
5. Experience shows that overpaying for tablets is not advisable. Among wearable devices, tablets are at the highest risk of screen breakage.
And laptops often survive in good working order until they become obsolete.
There's a contradiction here: a tablet should be affordable, powerful, have ports, and run a good OS.
But that's unrealistic. Cramming a tablet with extra features will make it a better computer replacement,
but it will also become thicker, heavier, and a poor portable tablet.
A tablet is good for working while standing and away from a desk, when using a laptop isn't appropriate.
In other situations, a laptop is more practical, lighter, and more durable.
PS: I use lowcost Android tablets so I can carry them around and don't mind breaking them.

I also use Windows tablets when I need to work with desktop Windows/Linux software.
I've never had a personal iPad, and while I enjoy drawing on them, they don't meet my other needs.
When a tablet with real Macos comes out, I'll definitely buy it.
