My views and my experience is sony Vaio laptop ?? is good and best performance that speakers, means hardware to software very impressive.my sony laptop is Vaio e series Intel i3 dual core processor and I was extended that RAM 2GB to 4GB . That time my opinion is good and the system is also good for it. Bhai sach Mai sony laptop hai hee aisa.but I don’t know why new products or laptop sell not in market.
