My ideal iPad is a 15" iPad Pro with an M4 Pro, combined with a Magic Keyboard with 2 Thunderbolt ports (that do both data & power) and a built-in second battery, that can run macOS and all my legacy software/workflows in a virtual machine, and can be operated entirely in clamshell mode from an external monitor. A drafting table when I need it, a pro workstation when I need that.
If such a machine existed, I would never buy a Mac again. That's what I've wanted on my desktop for the past decade
