My washing machine has 11 programs but I have only ever used one. My dishwasher has five but I've only ever used one. And I never change the microwave power settings, either. Manufacturers should focus on reliability and not options.
@anon_opin yeah, but have you considered, that another person does the same with a different setting? ,;)
And just for the record: on my WM I regularly use 7 programs and 3 on my dishwasher. ;)
