I work with a group of people that produce a similar small, portable  
cluster (http://LittleFe.net).  We mostly use our units for  
education, outreach, and training work.  Periodically it's handy to  
have one to run benchmarks on (as Joel described) but at ~6-20 GFLOPs  
they aren't rug burners.

On the other hand, with proper power engineering you can have a very  
efficient system that will work at home easily.  A 6 GFLOP LittleFe  
draws about 80 Watts.
