I've had the Samsung Series 7 NP700Z7C-S01US for the past 3 years and its been rock solid. Fast, big screen, and huge battery. Very, very good on power. Easily lasts 5 or 6 hours just browsing. Not sure if Samsung makes them anymore, but if you can find one, you won't regret it. The newer laptops barely beat it in specs.
