get a lock, get 2, get duct tape, get a security system, backup backup get an alarm
I had a PowerBook 667 stolen this past January from the studio at school-
It was locked to my desk, locked inside a cupboard, and in a room that can be accessed by 100 students- all of whom I am friends with- 3 janitors, and 5 (now 4) sleepy security guards.
I know 18 people who have had laptops stolen at college. DO NOT PUT IT DOWN. Pretend you're in naples and everyone's a gypsy- you cannot let your guard down (am i clear and threatening?) get an ipod- a big fat 30g and keep everything backed up all the time. You're parents homeowner's insurance will cover theft, but with a 500 deductible, and the police won't care who took it... esp the campus police... Kensington won't care, tho Kryptonite might- they'll replace a bike if someone can get through one of their locks... I bought a cheap broken iBook and fixed it up to bring with me whereever, and I keep the stealth PB locked.
As for tracking the IP if someone takes it, and plugs in, it will leave a mark on the network, but chances are, they won't be able to pinpoint where exactly- they were able to tell me what building my PB was in the day it was stolen
very very sad to know that someone on campus has your computer that you are paying for for the next 4 years...
so ya, keep it with you or keep it locked- if you take it out, someone knows you have an ill system, and might be watching... this is really morbid, i'm sorry, but you can't be too carefull...
and be ready for theft, if you have it backed up, and you have your receipts, and dad's got another $500 it won't hurt much more than some rough dental work
good luck at school
