I agree that if it is on top of your fiver, no one is going after it.
The subject of theft has been discussed here many times. I have concluded that in general, if the object in question, no matter what it is, is brand spanking new, then there is good chance someone will try to liberate it. Some thieves just can't help themselves around new stuff.
Case in point, I put new plastic fenders on my boat trailer. I went to a local lake and used the county owned boat launch. There is a guard at the gate, but nowhere else. When I returned, one fender was gone, and the other was 90% removed. I guess some people use the local landing as their parts depot. The fenders only cost about a $100, but they were too good for somebody to resist.
A new VuCube could have the same effect on the right thief.
