Summary: I have been extremely happy with T420 laptop. It is a bit heavy for travel but for the build quality definitively worth it. Laptop runs cool. If you want better resolution there is a 1600x900 model available, I wish the vertical resolution on this one was more. Battery life when playing video and surfing the net at the same time does not last 9 hours as advertised. The laptop has a thinkpad night light feature which is useful at night since T420 does not have back-lit keyboard. Speakers could be more loud. No complaints about CPU or graphics performance, handles the load very easily and is very responsive Note: I havent used it for any heavy gaming.
