Speaking only for myself, I'd love to have a modern netbook with great battery life and a decent keyboard. I'd carry that around with me all the time to hack on random bits of code or whatever when the mood strikes.

If I weren't completely tired of waiting for iPadOS to grow a Terminal.app, an iPad mini with a keyboard folio case would be nearly my ideal portable computer. For functionality, I'd vastly prefer something in that form factor that only supported text mode of something that had a beautiful GUI but no terminal. At least I could run emacs and fish shell there, and that'd cover 98% of my on-the-go needs.

Super bonus points if you can make the thing look cool at the same time, but that's just icing on the cake.
