The Toshiba Tecra R10-S4401 is a higher-end, 14.1" business notebook computer. It costs about $150 more than the R10-S4421 and differs in several ways. It utilizes a slightly slower, 2.26GHz dual-core CPU and features less storage capacity, but adds a gigabyte of RAM, a 64-bit OS option (Vista, however, not Windows 7), and 128 MB of discrete graphics memory, in the form of the Nvidia Quadro NVS 150M.
