The iPhone brings the user substantially more joy when using the product, compared to other smartphones.
When I say "joy" I also mean to indicate lack of frustration. The iPhone just works, and it works beautifully, in a way that other smartphones do not.
Now, why do I recommend paying for joy? Because you will be using your smartphone for probably multiple hours a day, for several years, and if you're slightly happier every time you use it, that adds up.
Downvoted for wildly subjective assertions about comparative merits of smartphones.
I personally have a Galaxy Nexus, and I much prefer the extra customisation and control I have over an Android system. It "just works beautifully", too. Feeling like I am in full control of a tiny, powerful computer in my pocket brings me a lot more joy than every time I've tried using an Iphone; where the lack of control made me feel like I was renting one of Apple's devices on a probationary period, rather than owning one myself.
So this is really a matter of preference; let's not pretend that the Iphone is simply an unequivocally "more joyful" or "better working" user experience.
I have often benefited from recommendations for Things I Didn't Know I Wanted.
Given that Less Wrong is a community of unusually intelligent, critical, and self-improvement-focused people, I suspect we can generate a pretty helpful thread of product recommendations — perhaps even a monthly thread of product recommendations.
