Investment research firm Piper Jaffray today held a conference call regarding teenage spending habits and statistics, which brought to light several figures about Apple devices and services. Of the students surveyed, the report found that 87-percent owned an MP3 player, and of those, 86-percent are iPod owners. This also reflected in the students' choice of music store, with iTunes sitting at 79-percent. The advent of other iPod-compatible music stores eroded iTunes' share slightly from 89-percent.

About 6-percent of students polled also revealed they own an iPhone, with an additional 9-percent saying they plan to own one within six months. This indicates that the iPhone's share has doubled from last fall, which Piper Jaffray believes could indicate that Apple will slightly exceed its goal of 10-percent market saturation.

In terms of competition, Real Networks' Rhapsody service is used by 2-percent of students polled, while Microsoft's Zune is the next most popular MP3 player, with 3-percent share.
