I use Puppy Linux on all my home systems with the exception of the wife's laptop. 2 old systems with K7 AMD's, an old KDS laptop using an Intel PIII CPU at 600 MHZ and my workhorse Dell Inspiron laptop (its got all my shop diagnostic software and manuals on it). I use 4.2 on the laptops and my main system and 5.0 on the guest bedroom system. Wonderful, stable operating system and it's TINY! My main system is running on an old 8 gig hard drive and I've used an old 4 gig on another system I was running.

The web browsers seem to be on the light side (not as fully integrated as with MS) but I'd never go back.
