Puppy Linux is the name. Super fast OS. Small distro with 128Mb RAM requirement. Imagine what you can do with your 1Gb RAM based netbook. A good rival to DSL or Linux Mint.
The apps also not a dissapointing factor. Feel bored with the Fedora/Ubuntu on old laptop? This OS has Seamonkey, the Modzilla based web browser. Other apps also looks OK to me. So?
