After using many brands found Lenovo G450 the best.This is an entry level product from Lenovo. I am using it since 2009. After little more then an year there was problem with the battery but got a new one at discounted price from amazon. So is the case with charger too.
The screen is LED lit. It weighs around 5 lbs which makes it comfortable to carry around. Though the price is on higher for Lenovo as compared to other brands but the quality comes at a cost.
