WHY THE PRICE IS JUSTIFIED

The teardown evidence is unusually strong: excellent shielding, real aluminum thermal mass, thoughtful power filtering and a useful power button. You pay for robust multi-display engineering, not luxury branding. Caveat: no downstream Thunderbolt ports.

DESIGN & ERGONOMICS

Professional rather than pretty; can stand vertically, includes front power button. Very high port density, but the front host cable and finicky microSD slot are drawbacks.
