It's more than just stuff
Sorry to hear what happened to you. When something like this happens it's not just the financial hit and frustration at lost data, but it can be quite unsettling for a long time that someone could physically rob you like that in what should feel like a safe place. I hope you are able to put it behind you quickly.
To the people saying "work in an office", I worked in an office in a serviced office building once, locked my laptop with a kensington lock to my desk, locked my office door, and it still got stolen. The serviced office company didn't trust the cleaners, so only gave them one set of keys; the cleaning company's solution - use the keys to open every door in the building (including the back door so their staff could go out and smoke), then lock them all again at the end. Unibody laptops may be better, but I came in to find the side panel of my PowerBook (this was a while ago) still attached to the lock and the rest gone. Apparently none of the security cameras were working. My insurance wouldn't pay because there was no forced entry, and the office denied all responsiblity (I fixed that by running up arrears to the tune of 1 laptop, then moving elsewhere with a letter explaining why).
I don't have stats, but I woud think daylight robbery like this is far less common than thefts from offices.
