Why Microsoft Sculpt Users Are Switching to X-Bows

Dr. Sig

The discontinuation of the Microsoft Sculpt has professionals scrambling for alternatives. Dr. Sig explains why "staggered" ergonomic keyboards are biomechanically flawed and how Radial-Columnar layouts offer the true medical intervention...

Dr. Sig

Does your aim feel "floaty" with a vertical mouse? Marketing calls it a learning curve, but physics calls it instability. We analyze how the "Lateral Force Vector" of vertical mice...
