My personal solution is a desktop and a 7-inch tablet. Sure the tablet loses some of the power as compared to a laptop, but huge portability gain. And it fits my use case. I don't write code while on the move. I do that at my desk. For all other use cases like consumption of data or even blogging, the tablet works.
Blogging with an onscreen keyboard is painful, and carrying around tablet + bluetooth keyboard is more cumbersome than a 9" or 11" "ultrabook". The ability to run old binary-only windows/x86 programs comes in handy too.
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.
So you leave the tablet at home? Do you keep your phone on you at home? (not criticizing, just curious).
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.
