As long as desktop games and live streaming/podcast exist, it's highly doubtful.
On top of that smartphone companies don't stand behind their products for long. Planned obsolescence on smartphones going up against people who have been upgrading their Rigs for years. Well over a decade for a lot of people.

Maybe they'll surprise and keep updating like LG but again I doubt it.

Great for those who aren't heavy users of a desktop computer but other than that, no.

Like someone else said above. Motorola has had this technology since like 2011 when I first used my Motorola Atrix 4G with it's lapdock and docking station. I laugh when people say Samsung with their Dex was thw first one...  :)  ;) sure!!!

I want to see a good convertible laptop-esque dock. But no, won't replace my PC. I like having non-proprietary software/hardware.

I used such PC mode with separate Moto Dock-station on my Motorola Droid RAZR in 2013 (8 years back). At that time it was already sufficient for office applications, but I was struggling with synchronization. Nowadays when 90% of  desktop applications are cloud-based synchro won't a problem anymore. Looking forward for Moto Mods comeback :)

You don't need a PC now, phones and tablets come with comparable computing power these days. My Snapdragon 888 phone benchmarks about as fast as a 2017 Macbook Pro with a core i7 7700HQ, which is plenty fast enough when I was just building large C++ codebases today in the Termux app (available at termux.com) on this phone. When I need a desktop mode, I just connect it to a USB hub which displays to a 28" monitor with Samsung Dex and type away with a full USB keyboard.

It is my phone, my web-surfing "tablet," and my PC. This is the future, and it will kill off the Wintel PC business.

XD

But can it run crysis?
