A friend told me once
"Give a developer a crap machine and they will write good code".
Which means that if a developer has a slow machine then they will optimise their experience with the machine to maximise efficiency/speed.
I will also say that my task bar consists of
Chrome, Chrome Canary, Firefox, Firefox Nightly, Edge, IE, Opera
as I do cross browser development in addition to server GUI access and if one breaks I have others.
