Ahh okay, my apologies. I saw this wasn't getting any replies and thought that might have been due to confusion caused by the poll. Feel free to edit the poll title again, sorry.
To answer this, it would come down to my Smartphone, desktop PC and iPad mini. Those are my primary devices. I have a new laptop on the way which might serve as my desktop replacement if I do decide to do some long-term travel in future.
Lugging around a desktop PC after all would be wholly impractical.
