Sony vaio comes in the market with some latest features and now a days basically preferred by user.
Like other companies a better user interface is also embedded. It available with 4GB DDR3 RAM with 1600MT/s memory speed still expendable up to 8GB easily. 750 GB inbuilt HDD is the better specification of this laptop, 15.5 inch display with 1366*768 Resolution is normal choice of users, support 802.11b/g/n wifi with 150mbps speed.
Availability of ports is still another better specification for me. I would like Hign Definition Audio with internal stereo speaker, this facility is also available.
Sony have some different qualities from another laptops, due to these all effective features, Sony is my favorite.
