With much thought I have formulated a marking scheme for all Linux distributions from LXDE, to Live CD to DVD and special dedicated distributions for kids, education and science.
For a Live LXDE I give 750 points.
For a good Live, stable and installable CD I give 1000 points.
My gold standard is PC Linux 2009.2 which gets 1200 well above the 1000 marks.
For a comprehensive DVD the minimum is 3000 but could go up to 4000 points on its needs.
I just tabulated Linux Mint 8 LXDE and got a score of 705 out of 750.
It has no games even for a light evening.
Taking from Ubuntu it major weakness is not having an administrator.
No Skype and K3B.
Otherwise it is sleek, beautiful and elegant.
I would like to give it a newbee.
