I can use dictation inside G Docs, true. I used it briefly 4 years ago when I temporarily could not type due to a repetitive stress injury in the hands that later healed (plus I moved to my current apartment where I have a spacious office and an ergonomic set-up and the repetitive stress injury happened when I worked out of my half of a small dinner table in the apartment I shared with a roommate where I only had a small bedroom and no office).

I bet G Docs dictation has improved by leaps and bounds since.

But what if I am, say, driving and have thoughts come to me? It happens often. Should I use the dictation inside the phone? Say, open G Docs app inside my Android?
