Software coder's laziness doubles every 18 months compensating Moore's law.
As a software engineer, I might object to that a little
Forgetting Windows (which gobbles far more power than this at each iteration), I can say that increased computing power lets you use language features that help you develop more code, faster. But not just more code - more robust & reliable code.
Windows & Office might add more glitz & feature bloat; real software tries to use the power to reduce bugs.
