It really worked well for my use case during the pandemic. I was in a research lab and while I did most of my computational work from home, when I had experiments to do I would go in, and used dex to update my data spreadsheets and collect imaging, upload to our computational cluster and be able to run some basic stuff on that through an ssh terminal. I was just using Google sheets for my basic data entry. And I had a dock already set up there for my laptop, which had attached ethernet, a monitor, keyboard, and mouse. So I could just plug my phone into the USB c and have an instant solution that worked just like a computer and connected to the secure network over ethernet (which was required for the fastest upload to the cluster).
The biggest limitations was only being able to have 5 windows open at once, but for the limited tasks I needed to do, it worked well enough.
