Only a couple of years ago I mainly used my phone. I didn't have my own computer, I was a teenager and had to use the family computer. And when I got my laptop my parents had put a time limit on it. So I tapped away on mobile most of the time, that includes mobile coding lol
However, now that I have my very own laptop without any boundaries I much prefer writing posts on computer. Occasionally I will write them on my phone but with the computer I'll actually get done more and find myself more comfortable with the keyboard.
