Produce Good Value "Green" Desktops & Laptops
There are many suggestions here for various changes that could make a PC "greener".
As part of the companies green credentials, I believe that not only should as many of these as possible be a "default" option, but there should be specific "greener" models of desktops and laptops.
These would have lower power usage and should be created and shipped in a more environmentally friendly way. Components, too, could be kept to a minimum - onboard graphics and sound and a removal in "legacy" ports. The desktop version of this could use laptop components to better embrace this idea.
The vast majority of PC users require one for emails, internet browsing and office applications - a low powered (but not under-powered) PC and laptop that are more than sufficient for this should be easy to produce.
