Sony jumps to bell-foot in the movement of portable computer of transistorized disc, releasing new Vaio without plate HDD. Vaio TZ18GN is 11.1 inches ultraportable with a disc transistorized 32GB, the duet of the core 2d’ Intel, the 1GB of the RAM and, unfortunately, the preloaded Vista. It weighs inside with 2.5 slender books, which is a little heavier than the lappie the transistorized disc lightest of the “world of Toshiba” with 1.73 book, but it is still pretty damnée light. The price to surround the HDD? $4.300, which is $700 more than the equivalent of 100GB HDD. Eesh.
