I'm on trains, busses, ... a lot, in general without internet. And I just take a laptop. Dont care about mac win or linux. I do some bookkeeping in a spreadsheet, or some programming, I write some text.
I hate to do anything productive on this (cheap) smartphone. No keyboard or mouse, basic software is missing,... It's great for consuming content, for a quick search or checking a map. But as soon as I want to do something, it all falls apart experience-wise. So I waste time in a game or HN when im on a bus, instead of doing something I like or have to.
So how do you people do it?
