Microsoft Sculpt Ergonomic Keyboard

Pros

• +Detached wireless numpad is a structural ergonomic advantage — mouse stays directly adjacent to keyboard body
• +Domed manta-ray surface reduces wrist pronation through keyboard geometry, not just key spacing
• +10+ year production run — owner failure data is extensive at 2+ and 4+ years of use
• +$60 entry is the lowest price for a proven-consensus ergonomic split with built-in palm rest on Amazon
• +Built-in palm rest sized to the Sculpt's dome geometry — not a generic pad added to a flat keyboard

Cons

• −Rubber dome keys degrade noticeably after 3-4 years of heavy daily typing
• −Dedicated USB receiver only — no Bluetooth; lose the receiver and the keyboard is non-functional
• −Aging 2013-era feature set — no backlight, no multi-device pairing, no USB passthrough
• −Windows-primary layout — macOS users must remap function row and modifier keys in software
