There are some modern conveniences I would not want to live without: running water and a washing machine for starters. There are some modern conveniences that are not really necessary, but they make life easier. I lived without a microwave for over four months until someone took mercy on my children and bought one. I was fine without it.
Another appliance I lived without is a clothes dryer. I lived for over two years without a clothes dryer and I really didn’t miss it! The clothes dryer would no longer dry the clothes. I didn’t want to hire an appliance repair person to come out to my place. I knew it was a minimum $85 for them to come out, plus parts, and any additional labor. I don’t like spending my money like that because sometimes I am cheap (not frugal).
