Iphone 5 not the thinnest smartphone in the world

duh?

There are tons of smartphones out there, especially when you considered the worldwide market, and they're all over the place on specs; some are very thin indeed. If Apple really did claim the iphone 5 was "thinnest" (I dunno if they did), they were being a bit silly, because there's almost certainly not any one specific spec on which the iphone 5 is "best."

That's not a ding against Apple at all, as their strength is not feature checklists, but making a very well-thought-out combination of features combined with high build-quality and solid support.

Most of the non-Apple "super thin" smartphones I've seen, for instance, are way too wide to really use comfortably with one hand. They seemed to follow the principle of "bigger (screen) is better!" without really thinking through all the repercussions of that, whereas Apple clearly did think about the issue when they increased their screen size.

Apple's presentations are typically full of impressive-sounding assertions that are some combination of misleading and outright false. I don't think anyone but the most naive takes Apple's claims at face value.

Make it: "the thinnest smartphone that matters".
