Some might argue the Samsung Galaxy, but the image associated with the galaxy is not one of luxury, but of practicality and a sacrifice in usability in exchange for for customization; the general Android vs. IOS argument.
Luxury breeds profit by turning users into silent evangelists/role models. Combine this with Apple's extremely strong ability to [1] set prices (Android is not a direct competitor, it's a whole different marketplace with its own internal competition) and [2] force costs onto partners (who wouldn't want to work with Apple and see that volume of business with those nice margins?) and it's no surprise that the iPhone is destroying competition on the profitability metric.
