Give any keyboard most of the benefits of a split keyboard by angling your hand/finger columns like `////\\\\` rather than like `\\\\\\\\` (as is commonly taught).

You should be typing "Z" with your ring finger, not pinky. 'WSZ' column, not 'WSX'.

Even the linked "Ultimate Hacking Keyboard" will require a VERY aggressive slanted placement of the left hand segment to give yourself comfortable inward left hand columns. Compare to Microsoft-style split/ergonomic keyboards, which angle `QAZ` inward or vertical.
