I don't think we'll add any special insurance when our daughter heads out to college next year. The things that'd matter MOST are her laptop and her phone; one because it's necessary for classes, the other because it allows her to communicate with us. In general, people don't steal clothes, and if she were to lose/ruin her ipod or something similar, she'd be unhappy but it wouldn't keep her from her studies.
I will, however, be big on prevention:
We'll be buying her a laptop either for Christmas or graduation, and I will get her the
Best Buy replacement warranty. A friend of ours bought this for a teenager, who ended up spilling a bowl of Captain Crunch on the laptop THE FIRST DAY SHE OWNED IT. The warranty replaced it. I don't normally buy specialty insurance like this, but
for a student who's going to eat, sleep, and live in one small dorm room . . . with a roommate . . . it seems like common sense.
Also, I'm going to buy her a laptop lock (about $20). A campus police officer told us at a college visit that laptop theft is the biggest crime on campus, and these little devices prevent
crimes of opportunity. These locks attach the laptop to a desk or bedframe so that the thief can't carry the laptop away.
Finally, I'm going to buy her some type of lockbox big enough for a wallet, camera, ipod, etc.
For college students, I think I believe more strongly in prevention than in insurance.
