This study shows that 16% of teens have use GPS on their cell phones. Nevertheless, when asked about the feature they want the most on their handset only 14% mention GPS, far down the list after SMS (45%), taking pictures/videos (29%), Internet (24%), music download (24%), TV (21%), IM (19%), video download (19%), FM radio(19%) and MMS (15%).
This lack of interest is probably due to the absence of compelling GPS applications for this demographics. For the time being US wireless carriers have mainly focused on in-car navigation applications that generate more profits with a price around 10US$ a month. Buddy finder type of applications are just nascent and have been so far limited to a few operators (Boost, Helio and more recently Sprint) due to privacy concerns. Additionally the strong appetite of their parents for child locator applications (see here) does probably not help much to make GPS the most needed feature.
