Why would i need an Iphone, a desktop, a laptop, and tablet?

Seems like everyone has all 4. Just wondering if there's really a reason to have all four?

The honest answer is; you don't.
Be grateful for what you do have, that's the important thing.

It depends how you use those if all you need is sending email and calling than an iphone is enough.
if you need to call and have desktop pc to create say html page than you need i phone and an desktop pc.

it depends on the need of the user however lot of people do not even fully use one device.

  • Which one is better? Tablet or Laptop? My sister might be getting an Iphone soon, I will become very jealous of her new phone, so I want to get a gift for christmas to make it equal. Should I get a tablet or a laptop? I also want to be able to play Minecraft since all my friends play it. Which one should I get? My price limit is $300.

  • Tablet snapshots on the Tablet and iPhone? I'm not very tech-savvy guy, go please forgive me. But does a Samsung note 10.1-the 2013- snapshot consume more memory space than a iPhone 4 in general? Here are the dimensions(again I do not know what I'm doing) Tablet(Note) 10.1" widescreen 1280x800 WXGA TFT LCD 149 pixels per inch (ppi) iPhone 4 640 x 960 pixels, 3.5 inches (~330 ppi)
  • Should I buy a laptop or a tablet? How do pages display on a tablet? I have an iPhone 6s Plus. It almost seems redundant to buy a tablet, but they are more affordable than a laptop. I prefer the way web pages display on a laptop. I have never had a tablet, do they display pages more like a phone or a laptop?
