[单项选择]Welcome, Freshmen. Have an iPod.
Taking a step that many professors may view as a bit counterproductive, some colleges and universities are doling out Apple iPhones and Internet-capable iPods to their students.
The always-on Internet devices raise some novel possibilities, like tracking where students gather together. With far less controversy, colleges could send messages about canceled classes, delayed buses, campus crises or just the cafeteria menu.
While schools emphasize its usefulness-online research in class and instant polling
of students, for example - a big part of the attraction is, undoubtedly, that the iPhone is cool and a hit with students. Being equipped with one of the most recent cutting-edge IT products could just help a college or university foster a cutting-edge reputation.
Apple stands to win as well, hooking more young consumers with decades of technology purchases ahead of them. The lone losers, some fear, could be professors.

C. have difficulty learning to handle the devices
