Totally practical! Might be worth checking that your laptop will be covered by your parents' household insurance. As long as you're careful, the risk of it being stolen is reduced to someone taking it if you leave it unattended (do not walk off from it in the library!! You won't believe how many people do this, it's so silly....) or someone mugging you (so always avoid dark alleyways, not trying to scare you!) Always lock your room when you leave for more than a 10 mins and count your bags when you leave a public spot. Enjoy university!
