Trend in MSU

I'm sorry to tell you, because I'm not a very fashionable guy, I do not really not what's the trend in MSU now. I guess maybe is iPod or iPhone or isomething? Just call them iX. I think its a trend in MSU because I saw almost everyone have a iX here. Even someone do not have, he/she still consider to by one. In fact, iX is absolutlly useful. It doesn't like the thing we used before that all things in the machine are not useful. Maybe that's why it can be a trend in MSU, even in the world!...
