This is really a good question and there are lots of aspect to say which is the best Laptop manufacturer. But over all I think Dell is most demanded among all and it provides the best customer service as far my experience. So i think Dell is the best. As it gives one year onsite guarantee for all laptops, This is really a great Laptop Manufacturer. It is quit user friendly and so people prefers it.
