Sony Vaio SB1Z9E / B 33.8 cm (13.3 inches) (Intel Core i5 2410M 2.3GHz, 6GB RAM, 500GB HDD, AMD HD 6470M, Blu ray, Win 7 Pro) I have the notebook a few days now and am very satisfied after the completion of installation. The problem of the very loud fan operation often described is to Update the bios completely eliminated. The update way, there is just above the left on the computer Vaio update. Could not be simpler. Otherwise: easy, fast and good quality. For me as a frequent traveler, the absolute recommendation, since there can only be 5 star it.
