About 4 years ago I got a 13.3" Thinkpad laptop to replace an old Chromebook for portable development, and installed Arch + i3 on it (btw). After a bit of ricing the configs, it started feeling really homey. I love using workspaces here! They feel perfectly suited for laptop screens which have minimal space, allowing me to keep my browser full-screen and my IDE full-screen while still quickly switching back and forth to reference one or the other.
On the other hand, I don’t really use workspaces when I’m on my desktop PC (I use a 27" monitor). I just installed KDE to get ahead of the Windows 10 EOL, and while I looked into combining i3 and KDE, I haven’t really felt the need for i3’s workspaces or using KDE’s virtual desktops. With a 27" monitor, I feel like there’s enough space to split my browser and IDE half-and-half on screen, and I’m ok using a file browser or terminal window as floating windows. Another consideration is that I’m always using a mouse on my desktop, so switching between workspaces with the keyboard wouldn’t feel as natural.
What about you? Do you use workspaces differently between devices? Does screen size affect your choices at all?
Using it to separate work from other uses makes sense to me - I think if I worked from my desktop rather than the company laptop, I’d be more inclined to use the virtual desktops.
