I'm 26...
and I tend to like things that may look outdated, but are proven and time-tested rather than things that are flashy and tech-laden. My wife is the opposite but that's OK.
One exception is that my wife and I both wanted to replace the ca. 2004 kitchen original to our house (white Frigidaire appliances) with stainless. I was hard-set on Whirlpool (or KitchenAid if I could get a good deal on them), she was drawn to the LG and Samsung packages, despite my warnings. I figured that the Whirlpool appliances would last longer and be easier to fix and get parts for, plus they were made in America, something that's important to me. The best thing was that the Whirlpool package that we bought was cheaper than the comparative LG or Samsung packages. No problems with any of the appliances so far. Not sure what would have happened if we bought Samsung or LG.
In 2015, I did slip up and bought a made-in-China Kenmore (LG) front load machine, on impulse and replaced my perfectly fine ca. 2004 Kenmore 90 Series (Whirlpool direct drive) washer (which, rest assured, I donated to ReStore). I only did it because Sears had quite the deal going for their rewards members. It was normally $800 at its lowest, but I walked out with that (and a BOL Kenmore dryer) for $550 total including tax. I really wanted a Speed Queen front load machine but that was a little steep at $2k. It's been four years since we've had this washer and we've had no problems at all, but if/when it gets replaced, I will buy a Speed Queen FL (I was thinking about buying a Whirlpool FL but the guys over at AW.org actually say that LG builds a better front loader. Imagine that...).
Other than that, I use an ancient (in phone years) Samsung Galaxy phone (and it's not even the higher end ones) but it serves my purposes well. My laptop is an off-lease ThinkPad that I bought off eBay, which was cheaper to buy than even some of the cheap, disposable new consumer grade laptops sold in the stores. Our TV in the living room is just a plain 42-incher 1080p from Walmart, it's only "smart" because that's all they sell now, but we've never connected it to the Internet. Instead, I built a HTPC for it since it offers more flexibility and doesn't have any of the spyware that smart TVs are known for. Our kitchen appliances are nice but nothing special, just a basic Oster blender, a basic KitchenAid stand mixer, a no-frills Kenmore toaster and a cheap but reliable Mr. Coffee coffeemaker (for me. My wife has Starbucks every morning), and other like items.
Oh, and vacuums, the subject matter at hand! After we started out with a Bissell PowerForce, I bought a Sanitaire SC886, even though my wife wanted a Dyson rather than that "old thing" (even though it was BRAND NEW in the box). A few years passed with just the Sanitaire and then the rest was history since January of this year when I randomly walked into a Goodwill and came out with a Sentria, with all attachments, for virtually nothing. In addition to that, I ordered my wife a Dyson Animal 2 that I gifted to her for her birthday, plus I have a Royal 884, a Hoover Convertible, a Kirby Avalir, Heritage II Legend (and soon, a Dual Sanitronic 50, which I will have on display in our foyer) in addition to my Rug Doctor X3. My wife loves the look of her Dyson but contends that MY vacuums seem (and sound) more powerful. However, since she was nice enough to let me have this "odd" hobby of buying thrift-store vacs and refurbishing them, I bought her what she wanted.
