Would you pay US$ 1.800, 00 for an iPhone 5s?

That's it's price here in Brazil, it's like 3.600, 00 Reais.
And many people buy it, when I say many people, I mean MANY people!

Added (1). Heyo: If I buy it on ebay, the brazilian fiscalization may take it.

No, I would not. Why is this question in R&S?

A dollar and 80 cents? Sure.

No, I don't buy apple products. Too expensive for the quality.

Nope…

I don't own one now…

Nah, I never even got an iPhone 1 - f**k iPhones! F**k Apple!

One dollsr 82 cents

That is crazy… IOS was great in 2010… It sucks now.
Those tiny screens…

Nope, I love my 4S and actually don't like the 5/5S. Just get a new 4S and enjoy. Its better, and doesn't feel so plasticy. Also, you should just buy it on ebay and amazon so you don't get ripped off like that.

1 dollar and 8 cents? Why not.

Assuming you mean One Thousand Eight Hundred American dollars while in America on American wages, no. Considering that your minimum wage is 674.96 Reais a month, still no. That's almost half a years wages. I did find a site that says it sells in Brazil between R1, 350 and R3, 000.

Iphones really hold their value well, so even when you want to sell or upgrade to a new version later, they are worth alot.

Not even close.
