Quick Verdict

Split keyboards fix the two habits that cause most typing discomfort: hunched shoulders and bent wrists. The XK01 separates the halves so you can set your own shoulder width, and the contoured key wells keep the wrists neutral. Typing speed dips for the first week, then recovers. For anyone typing several hours a day, it is the highest-impact upgrade on this list.

ProtoArc XK01 Split Ergonomic Keyboard scores 8.3 out of 10 overall. Its strongest area is reflected in the breakdown below, and the main tradeoff to weigh is that one to two week learning curve.
