Must admit, Puppy Linux is one of my favorites. I have an aging p1-133 laptop that has no problem running Puppy - (though it is a solid Win98se machine too.)

I realize that part of Puppy's charm is its small size, 60 meg, I still like Knoppix based Damn Small Linux at 50 megs. - more up to date. However, I must add that there are many versions of Puppy, and Chubby Puppy has Firefox and Open Office included. I think it comes in at around 110 megs, but I confess I really like it. I don't need a lot of bloat, just a few bells and whistles.

DSL is knoppix based, but Chubby Puppy is really a full-featured distro.
