I'm sure, because phone have multiple problems. One is the software, usually it's fisher-price levels of dumbed down. Buttons are huge because people have fat fingers.
So we can fix the software, but we still have hardware limitations. The hardware is small. The screen is small. There's no keyboard, only buttons on said screen. I can open a document on my phone, yes. But I see 1/10th the content I would on a computer screen - just because the screen is very small. I mean, we have these super high resolution displays... running at 400% scaling. Meanwhile, I have 1440p running at 100% on my computer.
That's, like, a lot more stuff that can be on the screen.
