In my opinion all of that works better on a laptop. I don't use any streaming services so that functionality is not important for me, but I do recognize that may be important for some.
For me carrying a tablet + laptop while traveling would just be wasted space when I can and prefer to do everything on the laptop anyways.
And you can’t download movies from streaming services on a laptop and I have unlimited cellular data on our laptops for $25 a month. When I say we travel a lot - I mean we were on a plane going somewhere over a dozen times last year and this year we are spending a month and half doing the digital nomad thing in another country right now and we will be doing one way trips across 4 cities for two months this summer.
And you don’t need a keyboard or mouse for Zoom.
Besides, you can’t get a MacBook with cellular and you can’t download movies to use offline with most streaming services on a Mac since most of them don’t have Mac apps.
We travel a lot. Even I take my laptop + iPad + external USB powered/USB video display that works with one USB cable. Most of the time I just use my external display. But I can use my iPad as a third display.
I really use my personal laptop for nothing. I left it at home while we are spending a month and a half in another country. When I get off work, I don’t think about using my computer for anything - I don’t do side projects and haven’t for 30 years.
