I'm on my way now to the gym. Thought that I'll try to sneak one post before I spend the good part of the rest of the afternoon working out.
I've always thought that Persona Paper is mobile friendly. The buttons are big enough to use even in a smaller device such as a tab or a smart phone. All the features in the desktop version are also available in the mobile version.
As for posting while on the road, I've always did it and in fact I love it. It offers a different freedom and perspective. Something about being on the road motivates me to write. When my smart phone isn't available or the situation calls that I give my undivided attention on the road, I make mental notes about topics I want to post about. When possible I jot down these notes in a journal I keep with me all the time.
I can say that some of my best posts were made while on the move.
Have you tried mobile posting? Time to go. I'm a block away from my gym.
