What a weird layout. If you all remember, the control key did pretty much nothing in Mac OS (and still doesn't, outside of Terminal). Yet, the control key is pretty large and placed in a favourable position.
My first computer was a BBC Micro, with its own bizarre arrow key arrangement (left/right above, up/down on the line below). I think I got the hang of them, although games never used the arrow keys, instead preferring left/right on one hand (e.g. A/Z), and up/down on the other (e.g. ,/.), a pattern that has sadly never come back.
However, after getting a PC, followed later by a Mac, I could have hacked at the throat (with the keyboard) of whoever came up with such a retarded arrow key layout. Probably one of Steve Jobs's more loopy moments, like prohibiting 3.5" floppy drives and expansion card slots.
Also, my keyboard, same layout as that, was one of the most abhorrent rubberdomes ever to see the light of day (second only to the suicide-or-homicide-inducing PowerBook 150 keyboard), whereas the one depicted above looks like one of the delectable ALPS models that I wish I'd had instead.
(Seriously, I should auction off my PowerBook 150 keyboard as a horror museum piece for keyboard nerds as it really is that bad.)
