Many connectivity options incl. RJ45-Ethernetuser-replaceable keyboard, chassis stays very cool even under load, good input devices, upgradeable RAM, matte, bright display, very configurable, good battery life. Battery life is worse than it should be, disappointing performance, gets loud under load, right side of the keyboard makes creaking noise. Big screen, big battery, but not big on performance – not as good as the smaller T14.
