Sony is hopping on the SSD laptop bandwagon, releasing a new Vaio without a platter HDD. The Vaio TZ18GN is an 11.1-inch ultraportable with a 32GB SSD, Intel Core 2 Duo, 1GB of RAM and, unfortunately, Vista preloaded. It weighs in at a svelte 2.5 pounds, which is a bit heftier than Toshiba's "world's lightest" SSD lappie at 1.73 pounds, but it's still pretty damned light. The price for ditching the HDD? $4,300, which is $700 more than the 100GB HDD equivalent. Eesh. [Aving]
