* **Advantages**:
  * **Dedicated Number Row**: Ideal for users who frequently input numbers, such as FPS gamers or data entry professionals.
  * **Compact Size**: Saves desk space while retaining essential keys.
* **Considerations**:
  * **Function Access**: May require function layers to access missing keys like arrows or function keys.
  * **Learning Curve**: Adjusting to function layers can take time.

* **Layout and Features**: These compact keyboards omit the number row, and the keys are at a more reachable distance.
* **Advantages**:
  * **Portability**: Their small size makes them easy to transport.
  * **Ergonomics**: Reduces finger travel distance, minimizing strain.
* **Considerations**:
  * **Layering System**: Extensive use of layers is necessary to access omitted keys, which can be challenging for some users.
