Pro 13
From VAIO Library
The Sony VAIO Pro 13 is a business-class ultrabook laptop computer that was released in 2013 by Sony. It features a 4th Gen Haswell Intel Core i5 or i7 ULV processor, and Intel HD 4400 integrated graphics. RAM options ranged from 4GB to 8GB, and is soldered on the motherboard. Contrary to popular belief, the SSD runs on the SATA 6GB/s interface instead of PCIe, and is of the M.2 2280 NGFF form. The case is made of flexible carbon fiber, which makes the laptop very light at only 1.066 kg (2.35 pounds). The display on this ultrabook was one of it's selling points, a Sony Triluminos 1080p IPS panel with 10 finger multi touchsupport.
