We use benchmarks largely as a test to refocus us outside the expected 
application area. They often (Actually very often) exercise corner 
cases. The metrics that we look at with great interest is the reference 
designs that are often created as we develop tools (and ISA's).

The concept that we are creating general purpose computers for anything 
has largely passed. The Laptop my wife uses is very much designed to do 
the things she does that requires good fast video processing and most 
need a good video co-processor. I do a lot of simulation and a little 
bit of image displays. The gamers mentioned elsewhere have different 
computing needs.

There are some application specific benchmarks for each of these area's 
and they help selecting a suitable personal computer. Running the 
benchmarks that my wife would use is unlikely to help me much in making 
my choice.
