I remember those days, Fvwm2[1] was brilliant with its multiple screens and controlling the mouse using arrow keys - good times. Amazingly difficult to config even if you could get Xconfig to support your setup (external refresh rates and supported screen sizes and drivers for video cards).

But over the years I've come to appreciate the simplicity of Mac. Initially it didn't even have multiple screens but you could install (I forget the name) an application that simulated the multiple screens of Fvwm2. Right from the start I was glad for the simplicity of just having everything work or it wasn't supported - there was no in-between.

Today I'm using Spaces with iTerm2 and Emacs as core development tools. Not much different from my Fvwm2, xterm and Emacs in xterm solution from 25 years ago. Pity really that nothing has fundamentally changed in code development.
