Depends on where I'm touring if I carry a computer or not, but it's certainly nice to have. I sent my first gen nexus 7 back a month into touring once and regretted it the next day. You never know when it'll come in handy. I do think it's a bit redundant if you have a smartphone. I didn't have one at the time. Now if I toured I would either just have the phone... most probably, or I'd carry a prepaid cheap phone and the computer.
