I _do_ think it's interesting to think "maybe buying 1 (even 2) desktops is actually better for me than buying 1 laptop", but I cannot bring my desktop to the library. I feel like this comment is on the same level as "don't buy a phone, you can do better with a laptop", which is absurd on a similar level without extra context.
What do you do for a phone? What works for me is: 6"+ phone that does anything I'd use a 7" tablet for (smartwatch means I don't need to take it out my pocket as often), 11" ultrabook for doing things on the go, 18" "desktop replacement"/"gaming laptop"/"luggable" for home and the occasional longer trip or LAN party. (I do have a desktop/"home server" but these days it's pretty much an oversized NAS).
I used to think that. But then i got the hang of it and now I do most of my writings on my tablet
> What do you do for a phone?
I don't have the use case for an expensive phone or even a data plan. I have a low end smart phone ($70) that I use mostly for just texts and calls. Even my whatsapp is on my tablet (needs manual .apk as playstore won't let you do this).
I am at my desk most of the day (office), so all Internet related things I do on desktop. After work hours I have my tablet at home so don't really need my phone for much else. Have a desktop at home as well.
For me it just meant one less thing to carry (you could see it as less getting rid of the tablet and more buying a tablet that does phone calls so that I don't have to carry a phone around). Public transport especially is where a 6-7" device is really handy, but I don't want to be carrying more than I can fit in my pockets.
