I bought Sony Vaio laptop last year is good screen and the Only thing is it has only 2GB of memory which is tad too low for this kind of system which was Windows 8 operation. But customer services of sony is very good then The only problem with this laptop is low RAM and you will have to upgrade it for smooth functioning.
This allows you to run more applications at the same time. It also has a 500 GB, and the additional 4 GB RAM its working fine and smooth.
