Smaller is better.

1. For phones, smaller phones are better: Less thumb pain for texting a lot, lighter weight (less strain on hands), generally cheaper than larger devices (iPhone as cheaper than iPhone Max), easier to use/text with one hand, and generally higher pixel density in display.
2. For cameras, point and shoot cameras as the best cameras: Fits in your front pocket, you can shoot with it all the time, you always have the camera with you and ready to shoot. Also in street photography, you are less suspicious looking, and attract less attention. RICOH GR II as a perfect camera.
3. Smaller laptops: Lighter, more compact, less strain when carrying and ability to take it with you everywhere you go. I’ll never buy a big laptop.
4. Smaller cars: Easier to park, ability to park in super small spots, cheaper, more affordable on gas, and generally more fun to drive. My 1990 Miata (no air conditioning, no power steering) as one of the most fun cars I’ve ever driven.
5. Video cameras: Instead of a big video camera, ease of using GoPro, your phone, or the new DJI Video vlogging camera. Smaller video camera setup easier to use, and less conspicuous in public.
6. Smaller headphones: Better to use in-ear monitor headphones than the big noise canceling ones. More compactable in your bag, and less bulk and weight when traveling. Or in general, the joy of the new Apple Airpods for smallness and ease of use.
