Old PC + Linux = Green Computing
So I hear the UK government has concluded that Linux is more eco-friendly than Windows. The reason, of course, is that Windows users are forced to replace their computers more frequently, resulting in more e-waste. I can't say I'm surprised (though, admittedly, I can't say the environment is the reason I run Linux, either). In recent years, Windows has more or less become completely irrelevant to me, so I haven't tried Vista myself, but I have of course heard of its outrageous hardware requirements. And Windows has always seemed more resource-hungry to me than Linux.
My main computer is an Acer Ferrari 3000 laptop (yes, that bright red one). It's, um, around four years old, maybe, and only has 384 MB of RAM, so it appears I couldn't run Vista on it even if I wanted to. And I don't even know how old my server is. I got it for free several years ago when, emblematically, it had to be replaced because of some software upgrade (I know the people I got it from ran Windows on it, but I don't know which version). I have since stuck a couple of additional hard disks in it, but it's otherwise the same old clunker as ever. Despite this, using it as a file and web server, and even for watching movies, is no problem at all. I could probably have done this, more or less, under Windows too, but that would have meant sticking with some old and out-of-date version of the OS. Instead, I run a somewhat recent version of Fedora on it, and plan on upgrading it to the latest Xubuntu... some day when I have the time.
