>Apple is "trendy". Nothing more.

>And for all those kids that voted for Obama and think the iPod is the only way to be cool, Obama uses a Zune.

>>Spent a day with college kids in the US last week. Every one of them already had or intended to upgrade to an iPhone, though some planned to wait until May when the new version is expected with a better camera, higher resolution and possibly a pressure-sensitive back.

>>Their reason? The gravity sensor, the 3G and the apps... but in the end, because everybody that matters to them already has one. I did quiz them about other options (like Windows and dual-sim options) and learned that Windows is for grey-hairs and that the real battle is between Apple and the Google Empire. Some of these kids had near-new motorola/nokias and even a few Androids, but still wanted to change. Seems Apple is doing something right and that the high cost itself may represent some sort of badge of honor, just like a Cartier watch I guess.
