I once had a very expensive leather backpack stolen. Inside were my passport, a DSLR, laptop, and some other things. Total value was in the thousands, easily.

It bothered me (and was a financial burden) when that stuff was stolen. But when my $400 hybrid bike was stolen a few years later, it bothered me twice as much, if not more. I think because a bike is a durable, daily thing that you come to depend on, while expensive gadgets are just gadgets.
