* Screen quality (IPS vs TN, glare vs anti-glare, etc)
* Keyboard layout and quality (yes, this matter A LOT if you type all day on the computer)
* Driver compatibility (since Linux is mentioned)
* Weight, roughness (or beat-up factor), portability factors, battery life, modularity, expansion ports... the list goes on.
