Got an old laptop? look here :)
I noticed lot's and lot's of threads with people saying ' I have an old laptop, what linux distro should I get?' and the answer is there are many, but there are two I would recommend that I have been running on an old 133mhz laptop I found at home, here they are:
Slackware ( that distro amazes me )
Damnsmall linux (aka DSL)
on both of these I am running fluxbox because, well I like it and it doesnt take up many resources.
So here it is, look here if you have an old laptop, hope this helps.
