I've never used them for programming / building things, but that's somewhat based on limited type of development I did. I can see macro commands being useful if I frequently need to recompile / deploy / make / push / merge / whatever. More structural type things than strict programming which I've found not repetitive enough. That being said I've used programmable keyboards extensively for macros when in sysadmin / ops roles in the past though, from simple one line commands and shortcuts, to "do 80% of work for me". Never used programmable mice though as the buttons seemed too fiddly / inconsistent for me to be 101% which one I'm hitting.
