It's a cool trick though.
Wish this worked with iOS.
Unless you just want to not be carrying anything.
Slap a 1080p or 2560p panel in it, and the laptop is a monster!
What newer laptops have is USB-C/TB3 and that allows for eGPU. Which means you no longer need to own a PC if you're a gamer (and don't wanna opt for game console).
I found the smallest sling bag that it would fit inside, and quickly became accustomed to carrying it at all times.
When my Nexus 5 died, I barely felt it. I went months without a phone because it just wasn't a pressing issue.
There's no way I'd trade it for a phone dock and desktop peripherals.
I've been carrying a backpack for work for, I dunno, 4 years now? Lately I've taken to just leaving my laptop at work on weekends and I really enjoy the trip to/from the office those days. I commute via public transit or walk, it's only 2 miles and we have decent busses here in Philly. Not having to deal with a bag of any kind is really nice.
The current MacBook Air has slower CPU (single- and multi-core) compared to the latest iPhone 8/X.
At the end of the day, I'd love to grab my phone off a cradle and then, when I get home, if I need to keep working, drop it in a different cradle and have my window session ready and waiting for me. As a GCP user, basically 100% of my development consists of browser sessions and tmux sessions. That should be really portable state on a phone.
I don't know if this really solves that, though ...
I would like to maintain the same compute environment from phone to laptop but I would still need to bring the laptop (or, rather, the laptop shaped dock) with me everywhere.
This is because you can't possibly plug untrusted/unknown devices into computers you own. There is no way I am plugging my "CPU" into a hotel/airport/Regus workstation.
So that's a market size of one then? You could sell this solution to Samsung, and pretty much nobody else.
But no, it has not happened. We still fumble over connectors.
Given my failed ability to get anyone interested in going Chromecast I doubt I could persuade anyone to get DeX sorted for the meeting rooms.
But, the older people I know have PCs that sit around collecting dust and that they are not at all comfortable in using. But they do have phones that they use every day to communicate via text messaging, email and Facebook.
This seems like a good solution to bridge the gap for them on the occasions where they are interested in a desktop experience as it provides a familiar environment using the phone OS and removes the worry about managing or navigating a desktop environment.
But then you've got to add a keyboard and a mouse and probably the biggest problem, you've got to figure some way of getting the monitor to an ergonomic height.
