Well, am coming on in defence of both machines. When I lived in a house, did have a tumble dryer in utility room but used rarely - in summer the whirlygig in the garden, and in winter an airer in utility room. Now I live in a flat, use the my heatpump tumble dryer with every wash. Wonderful machine, reasonably economic to run. Means that a load of washing is done, dried and put away within a few hours. Nothing hanging around anywhere in the flat.
Microwaves I have had for so very many years. My current one replaces a big oven as it is a combi-microwave. More economic for me to run that a normal large oven. Do everything in it, from cooking my porridge in the morning, through baking cakes, making my bread, and cooking my fresh salmon, or chicken, etc for my evening meal.
Thank goodness we have moved on from a large pot held over an open fire, or even a coal fired range being on all the time. I love modern kitchen items.
Although there is just me.....I still have a narrow dishwasher, and use this just for when I have company for a meal - or to give my glassware a wash through every so often - it comes up so sparkling.
Also love my toaster, and (or me) my electric egg boiler and my hot water gadget -although when I get my kitchen refitted, I will change that out for one of those boiling water taps.
