Reviews for the Lenovo ThinkPad T420-4178-9YG

With its epic battery life, awesome keyboard, solid sound, durable design, and high-res screen, the ThinkPad T420 offers nearly everything you'd want in a 14-inch business system for a good price. If you're looking for something a bit lighter, consider the ThinkPad T420s, which weighs 1.2 pounds less but lasts half as long on a charge. However, if you want the ultimate thin-and-light productivity powerhouse, the ThinkPad T420 should be at the top of your list.

Above all, this display size is used for subnotebooks, ultrabooks and convertibles. For all three types, this size is quite large. The biggest variety of subnotebooks is represented with this size.

Large display-sizes allow higher resolutions. So, details like letters are bigger. On the other hand, the power consumption is lower with small screen diagonals and the devices are smaller, more lightweight and cheaper.
