With voice to speech and predictive text I can write text on my tiny mobile keyboard pretty fast with good enough accuracy for correspondence type messages. I can do this from anywhere on Earth and I won't have to bring a heavy laptop. Every pound I can cut helps when I have to travel. That said I usually bring a small laptop when I travel, but it usually stays in my luggage unless absolutely necessary.
