Toshiba has released two ultraportable notebooks intended to be ecologically friendly -- but they're not ultra-low-price. The R600 comes in two models, the S4201 for $2,099, and the S4202 for $2,999. Each has a 12.1-inch screen and starts at 2.4 pounds. The S4201 comes with a 160GB hard disk, while the S4202 comes with a 128 GB flash disk. They both include an optical disc drive and support WiMAX. According to Toshiba, the R600 is ranked as one of the most eco-conscious laptop computers sold in the US by the federal Electronic Product Environmental Assessment Tool (EPEAT). That is actually sort of true, though there are a total of 130 notebooks that received the same ranking and point score as the R600. Indeed, only one notebook beats it: the Toshiba R500.
