The iPhone has an unusually high adoption rate among teenagers, a new survey suggests. Having polled 980 teenage students, the research firm Piper Jaffray says that 3 percent of the group already had an iPhone, and that another 9 percent expected to buy an iPhone within six months. Adoption rates were higher in the more restricted parental survey, where 4.2 percent of 212 people had an iPhone. Fortune Magazine casts some doubt on a larger application of these figures, however: the publication notes that there approximately 28 million teens in the US, of which 3 percent would be 840,000, or the vast majority of the 1.1 million iPhones sold to date. Fortune argues that the Piper Jaffray sample is likely taken from a "tech-savvy, upper-middle-class" population.

The same survey indicates that the iPod's share of the MP3 player market has remained steady, at 82 percent; the desire to buy a player within the next year has risen though, from 42 percent to 47. Apple has taken a hit in the realm of online music sales, as while 36 percent of students said they buy music online, use of the iTunes Store in this group has slid 10 percent to 79 percent.
