If I were you, I'd go for an Acer or a Dell here in India. They have really good service centers. HP and Compaq are bad cos their products last and work perfectly till the warranty ends, 80% of the cases have been that laptops from them get major expenses one month after the expiry of the Warranty.
Sony's are overpriced not worth the premium, Dell's expensive too but they deliver what they charge for. All though a little more then what it costs but yes, their products have a long life.
Acer's are poor mans Laptops, they deliver the best of hardware at the cheapest of prices and literally no problems if used with care.
Thanks a lot alyoshka! it helped me really.
