Well for starters, the Surface Book starts at $1500. The 10.5" iPad Pro with keyboard starts at $800, and the 12.9" with keyboard starts at $1000.
A better comparison would be the Surface Pro, which starts at about the same price as the 12.9" iPad Pro with keyboard. However, that configuration has a core m3 processor and 4GB of RAM. I'm pretty sure the iPad Pro will outperform the Surface Pro pretty handily until you get a model with 8GB of RAM, which will put you back about the same price as the Surface Book ($1500).
If you can point me towards a two-in-one that's half the price of the 10.5" iPad Pro with keyboard and performs as well, I'll be very impressed. $400 dollars doesn't buy a lot of computer. Even if you can find one, I'm 100% sure you won't find one that has the same build quality and battery life that the iPad Pro does.
I'd also be impressed if you could point be towards any non iOS tablet that works just as well as an iPad. Using iOS on a tablet is far, far superior in my opinion to Android or Windows. Android has nowhere near the app selection and Windows still feels like you should be using a keyboard and mouse for most things.
The real issue here, though, is that more and more people have absolutely no need for an "actual computer" and so they don't care if the iPad fits that definition or not. For some it's actually a negative because of the added complexity.
