How much life do you think you could get out of it, if all the software was written to be power-aware? Taking a rough figure of 2 hours in the current situation you would need to at least triple the life. Surely you aren't going to manage to get that much out of it? I guess this also begs the question- are we wasting that much power on our desktop systems? -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/linux_adm/list-faq.html
