For example Smartphone is clear.
What else? Laptops etc.
Why do you think you should own a smartphone? There should also be people who still get along wonderfully without.
It all depends on the person. If you don't need more than a cell phone, alarm clock, tv and pc, that's fine. But if you play Nintendo like I do from time to time (in my case 3Ds & Switch) and draw digitally (I have an iPad for that) then you have more. Depending on how you can afford it, I guess.
Smartphone, PC, electric shaver, radio, etc.
Huh? I don't need a smartphone or laptop! My electrical appliances are mainly in the kitchen! First of all the coffee machine! Then stove, oven, microwave, toaster, mixer, electr. Can opener, etc.
I have at least several small electrical devices, apart from a cell phone or a printer or PC.
