I don't want to divert the thread - it might make an interesting new one - but I was rather alarmed by Mr Bungle's advice re energy use. I have always used old machines - this one is an Acer Aspire T650 - 2.93 GHz - I was given maybe 10 years ago, and runs Lububtu. This, below, is my present understanding:
'As long as your computer goes into sleep/standby when you're not using it, your computer doesn't use squat for electricity, compared to the rest of your household. You'll save a lot more energy by addressing your heating, cooling, and lighting use rather than obsessing over your computer. For most people, their computers' energy use is not a significant portion of their total use, even if they use their computers a lot. '
