Oh no....not good. We were burgled in summer 09 when we were on holiday. The b*ggers kicked the front door in one lunchtime, kicked the inner door in and nicked 3 laptops and a bag to put them in. Arses. But they didn't take the spare set of house keys we'd left in a drawer upstairs, or other small (and easily sellable) items like a digital radio. Weird. The front door was then wide open and glass all over the place until a friend went round to feed the cat at 6pm and she called us so we rushed home (were only a couple of hours away).
Police were very good - but no fingerprints were left, so couldn't really do much. We had to get a new front door and inner door, and claim for laptops obviously; all this was only a month after being robbed on holiday in france and losing ipods, passports, house keys, wallet, memory card for camera (with Tour de France film/pics on it!!!!!!!!!), tickets home.... all the important stuff. The insurers (MoreThan) were great, on both occasions.
Definitely get the locks changed, especially as they have your keys!
