Also, Apple definitely had the nubbins correct (D and K) and foolishly surrendered that as well: they're easier to notice when they're under the wrong fingers. With them on F and J, if your hand is offset towards the outside you're forced to notice the absence of the nubs.
Oh well, just like caps lock can be remapped, so can my keycaps be swapped (perks of blank keyboards I guess), though it'd be even harder to use a keyboard that's not mine I guess.
In terms of ergonomics, the curled-left-thumb "Command" activation (it's where Alt is on a normal keyboard) is my favorite thing about the Mac key layout.
