You underestimate how much professional work is done via the web browser and RDP these days. I am a Cloud Engineer (basically do virtualization work) and could easily get by using a phone as my main work system. Most of the time I am using MS office apps that are basically just wrappers for their web versions anyways, and on a VPN connected to some server. All doable from samsung dex already, I just dont use it because multi monitor is important to my work flow
