Build and Design
The T420 looks ... pretty much like what ThinkPads have always looked like. It's a classic design that places function over form. Take the exterior plastics, for example. They have a matte texture which is scratch-resistant and does not show fingerprints/dust (as opposed to glossy plastic). The plastics are of good quality and don't rattle when tapped by a fingernail. The fit and finish is consistent all over - there are no rough edges and gaps between the various pieces are the same.

Ports and Features
The T420 has a solid array of input and output ports. It's also worth noting the T420 has a docking station port on its underside - Lenovo sells several different models, all offering plug-and-play compatibility and connections to many more ports. This functionality is a feature of a true business notebook; lower-end "business" notebooks do not have them, nor do consumer models. All picture descriptions are left to right.
