I would suggest you to buy hp laptop with good configurations .Acer also launches good products.I am using tosiba laptop. It is also good laptop,its been two years and i haven't find any single problem in it.
In India there are different kinds of companies which are providing laptops like Dell,IBM,Lenovo etc.But the quality of aptop depends on its configuration. You should firstly think what is the configuration of laptop do you need then can move t any of company to buy the laptop of required configuartion
Earlier I had the notion that DEll is HELL but my notion got changed when I got some positive feed backs and reviews from some of my friends who are using it... :)
