No one will ever convince me that a laptop with a web cam whose position is limited to looking straight up your nose is quality.
I primarily navigate by keyboard, so the difference between an acceptable and amazing trackpad is pretty minimal for my preferences. On the other hand, port wonkiness, temperamental wifi, okay keys, mediocre battery, driver issues and an utterly useless webcam convinced me to ditch the XPS the first chance I got. It's amazing I used it nearly 18 months.
