The article kind of misses the point.
The reason why people are leaving the Japanese phones for the iPhone is because Japanese phone interfaces SUCK BALLS. And they have ALWAYS sucked. I suffered through 5 years of one phone after another being such a terrible user experience that I think it scarred me for life. And don't even get me started with Sony, who replaced the perfectly functioning joypad in their phones (which USED to be the best) with that stupid "sony" sidewheel they spent so much money developing and insisted on putting in every product, whether it made sense or not.
The fact remains, emoji ARE important. Easy text input IS important. Being able to pay for stuff at the combini with your phone IS important. It's just that having apps, and a UI that doesn't suck balls is even more important.
iPhone took YEARS to penetrate the Japanese market, precisely because it didn't have the features that customers wanted, and they spoke with their wallets, buying the Japanese models. But now that app and smartphone fever has finally landed, people are more willing to compromise.
But the point is, they SHOULDN'T have to compromise. That's just Apple deciding what people will use, even if it's the wrong thing. It's taking a little bit of good advice to such an extreme that what appears on the surface "visionary" would upon closer inspection reveal itself as insanity. Hubris has a way of creeping up on you when your power remains unchecked for too long.
Yeah, Sony used to be good, but then again they used to make good products. Once their arrogance got the better of them, their products started to suffer. My first Vaio was awesome. Sleek, light, and fast. My last Vaio was practically useless out of the box. It took me 3 HOURS to remove all the crapware they loaded into it, which slowed it down so badly that it was almost unusable. Oh, and it had that stupid useless Sony sidewheel on it, and their incompatible-because-we-said-so memory stick port too. I shudder to think of how the average user would endure with such a monstrosity.
