I think you may like PureOS
its based on debian squeeze
http://pureos.org/index.php?lang=english
because their based on both debian and linux live scripts(slax)
the persistent feature is different
PureOS uses persistence the way slax does
meaning you wont have to partition usb,etc
the persistence file(a file of ? size to hold your settings, files, etc)
will be kept inside the PureOS folder
theres a big openoffice version and a smaller version
what do you think?
