Over the years, I’ve gone through times where I really wanted to optimize the use of my mobile devices. I don’t mean “optimize” in terms of removing things, but the opposite — seeing how much work could be done on mobile-only.
We had a client a few years ago that shared a Powerpoint presentation with us, and he was proud of the fact that he did it entirely on his phone during breaks in his day. It was impressive, but it sounded like an awful task to try to do on there!
These days I’m a bit more focused on keeping things specifically for “computer” use versus “mobile” use. For example, every word of blog post that I write (including this one) is written a computer. While I add quick notes from my phone, I don’t even start a draft on there. It’s a computer task. I still keep most apps on my phone just in case I need them, but I’m trying to limit use on there to do the “real” work on my computer.
This means I’m old.

How about you?
Do you separate tasks for phone versus computer? Do you ever make big purchases on your phone, or is that “laptop activity”?
