Yup, absolutely. It's definitely true that it's better to have a more-capable device in your pocket than a less-capable one when a laptop or desktop isn't feasible - I completely agree.

I just wanted to point out that these devices are still significantly less efficient than a laptop or a desktop, because it's non-obvious to some people - including the throw10920 a decade ago, who thought that doing development on a phone when they had access to a desktop was a good idea. I wouldn't want to give other people that same impression, just like I wished I had never gotten it myself.
