Columnar keyboard planes
Key wells angle away from the midline so fingers travel shorter vertical paths. Manufacturers document row offsets in millimeters; we echo those figures without ranking brands.
Thumb clusters move modifier keys closer to the space row, which shortens thumb travel for some typing styles.
Pointing device arcs
Trackballs keep the sensor static while the thumb or fingers roll the sphere. Vertical mice rotate the grip axis roughly ninety degrees compared with flat mice.
We photograph each category under the same lighting so comparisons focus on silhouette instead of marketing finishes.
Maintenance rhythm
Dust optical sensors gently, tighten arm bolts seasonally, and relabel adapters when you swap machines. Predictable maintenance reduces sudden hardware swaps.
