I must give props to Dell for taking a big step towards greener computing with their new Studio Hybrid lineup. In terms of design, I'm very picky about what I like and Dell has been producing some pretty good looking hardware (although I prefer Mac OS X over Windows for software). I applaud Dell for making a machine with a tiny form factor that consumes 70% less energy than standard computers and ships in 95% recyclable materials.
The reason why I am promoting this is simply because I believe it is a step in the right direction for a major market holder in the industry. Not to worry, the Hybrid line comes with a variety of options to customize it to your needs. You will not only save energy but you'll also have a smaller carbon footprint.
Apple has already begun its process of making their machines as green as possible by using highly recyclable materials (aluminum), smaller packaging, mercury-free LCD backlights, and more. It makes feel that much better about companies doing the right thing, and it should be the same with you.
