The Sony Vaio SR series was a line of consumer-grade notebook computers from Sony introduced in July/August 2008 to replace the Sony Vaio C series range (they could also be seen as competing with the lower end SZ models), as a part of the Intel Centrino 2 launch.
They are equipped with a 13.3" screen and weigh approximately 1.95kg, significantly lighter than the C series, similar to the non-premium carbon fiber models of the SZ, but significantly heavier than the Z Series (which, unlike the SR, uses carbon fiber to reduce weight).
As with the SZ and C series laptops, the SR uses a 16:10 ratio 1280x800 LED-backlit screen.
Compared with the higher-end Z series, which has GeForce 9300M GS graphics (producing less heat in the smaller chassis of the Z series), the ATI-equipped SR offers better gaming performance, marking it out as the consumer/gamer's option.
Options available on the Z series that were not available on the SR are WWAN (HSDPA), and RAID SSD.
