She should have a look at the Huawei Matebook. You can transform the screen into a big desktop sized screen. The only thing missing is a stand that brings it to an ergonomic height.

I think you mean the Matebook Fold?

Surely the other missing thing is that it only runs a proprietary OS that nobody except Chinese companies develop apps for?

Or, she could sit down and think really hard about what she needs, come up with a neat technical solution, and share her thinking with a community that loves this stuff.

Glad she didn't go shopping.
