Laptop manufacturers take advantage of the energy efficiency of the Intel Core Duo processor to extend battery life, and now computer maker Jinglehorse uses that same efficiency to allow its EcoSystem PC to consume 75% less energy than its Pentium 4 counterparts. These electricity-sipping boxes only use about 44 watts while they're sitting still and 75 watts with the pedal to the metal.
Plus, all that energy savings results in less heat, requiring smaller, quieter, and less frequently-running fans. For those of us who leave our computers on 24/7, this $895 computer might just pay for itself after a few years. Good deal.
