I don’t believe there is an ideal keyboard or layout.

Anyway, I am reminded of Xah Lee, http://xahlee.info/kbd/keyboarding.html

One of his insights is that Alt and Ctl keys on both sides of the spacebar improves ergonomics (particularly for eMacs). I still find it useful years after I stopped using eMacs. That means I favor Thinkpads.

Which reminds me that keyboard ergonomics include track pads, mice, and other pointing devices in many typical contemporary uses, e.g. if you mouse right hand, the left side of your keyboard needs to do more.
