Exactly. The hardware is already powerful enough. An iPad Pro with unlocked virtualization and a proper Linux VM would be an amazing travel dev machine. This is the reason I made this project, and I am still exploring for other tablets with better resolution and more resources.
That is also my dream, iPads Pro are very expensive but the hardware is so good (that is including the Magic Keyboard). BTW OP, have you ever tried a hybrid Chromebook tablet like Lenovo Duet 3? This is my favorite device for travel exactly because it is so good as a small Linux machine. Crostini fits the "I want to run a Linux VM". You can even use postmarketOS if you want an even more "traditional" Linux experience…
I usually prefer cheap devices for travel, because you never know when something gets lost, broken, or stolen. This tablet fits that well, Android for the kids or for testing an app, and Linux when I need something more specific.
