Here we have 2 comparable laptops, pretty much identical specs.
Macbook:
11-inch MacBook Air $1099
Dell:
$542
Out the gate, spec wise the Dell is already better than the Apple due to having a larger HD, newer gen Intel Processor, and more Ram. But I can hear people crying saying that the MacBook comes with a SSD and that's uber important. So, for the sake of the argument we'll tack on an extra $80 to the Dell for a 256GB SSD, so we're looking at a grand total of $632 for the Dell vs $1099 for the Apple.
Now, according to a quick Google search the average lifespan of a laptop is 3 - 4 years. Now, say you buy the Dell and almost every major thing that can go wrong, goes wrong. Motherboard goes bad, Hard Drive dies, Screen stops working, power brick dies.
Motherboard: $130
Hard Drive: $80
Screen Replacement: $110
Power Brick: $40
Total = $380
+ Original cost = $1012
Now, you're probably thinking well that's about right, I might as well get the Mac off GP. Now, let's say just one thing goes wrong on the Mac:
Screen Replacement: $300
Motherboard Replacement: $250
Charger(We all know Apple chargers are shyt): $79
*Disclaimer: Don't quote me on any of this as it was all done with quick google searches and with the first few results.
My point is tho that there's no logical reason for anyone to pay that much more for a laptop other than the fact you want OSX or to say you have a Macbook. And really if you want OXS you can hack up a version for Windows. I'm not sure if that's still a thing but I remember doing it some years back on a Toshiba.
It's really like buying a BMW vs buying a Camry. I mean if you're financially able to then hell why not?
