Toshiba presents the new Dynabook Satellite T31 laptop. Interestingly, this 15-inch notebook PC comes preloaded with both Windows XP Professionals and Windows Vista operating system, thus allowing you to choose which one you want. Personally, I only recommend Vista if you configure this machine with at least 2GB of RAM. Other features include a 2GHz Intel Core 2 Duo T7250 processor, an Intel GM965 Express chipset, and a WXGA display. No words on pricing and availability.
