Dell must have one seriously disturbing definition of "green" if they consider themselves "the 'greenest' technology company on the planet". The fact that they may be offering efficient power supplies means nothing. In its big push for sales and profit, Dell pushes low-quality machines at both residential and business customers. These machines either break down just before or just after the warranty expires, or they need to be replaced within one or two years because they're so under-powered they can't even run a web browser and Solitaire at the same time. So what happens? All those under-powered machines are thrown into the trash, and everyone buys a new machine. That's great for Dell's bottom line, but it's horrible for the environment. It most certainly cannot even remotely be considered "green" unless you're using the old definition of "green", as in "seeing green" = "greedy". But using that definition, I'd say Microsoft, Apple, and Google are all more "green" than Dell (though not by much).
