Every home has that point when appliances start to die, and that's what happening at our home atm. I'm researching new ones for last few months so I believe I'm up to date with new technologies available to masses. (and no, we're not super rich)
Smart appliances are not so expensive as they used to be. Smart TVs mostly have the same price as normal ones and washers are just slightly more expensive. And most of small gadgets to improve your smart home can be found online for few bucks.
As more technology and innovations are brought to the market, automation especially IOT will make the home experience simpler and more pleasant as you mentioned. However, as this technology is relatively new, the testing phase will see the cleaning out of multiple products that are replaced by better alternatives.
