I will keep the 2008 version
about a year ago I have installed openSuse 10 on one of my customers PC and it was outdated at this point
already, but his PC was like 1Ghz with 256 ram and each Distribution that I had at this moment refused to
install.. he was happily surfing the net for one year, and this year he bought an new PC with Ubuntu.
Unless you have security paranoja the 2008 will serve you well.. and you must know there are tons of updates
for 2009.1 already..
