My gardener once left one of his shovels in my yard for a few hours. During that time, someone stole it. I asked him why someone would steal a shovel, and he said because it was a $150 shovel.
It's always interesting to see how tools of different trades scale. I got into woodworking a while back and discovered Festool. Turns out there is a decent difference between a $200 miter and a $1300 miter. Though much like audio equipment or anything else really there are certainly diminishing returns.
Moral of story.. don't leave nice shovels in the yard and don't install crappy spyware OS like Windows on nice new computer.
