I'd completely forgotten about the HP Omnibook with that crazy j-mouse. The IBM 200 and X series were years
after the 505G (I own one of every model of IBM subnotebook). As I wrote earlier, when the 505G arrived, IBM had the 701C and moved to the 560 (kite). Ditto the Lifebook. The Libretto 50 and 70 were, like the IBM PC110, attempts at a usable palmtop, rather than subnotebooks.
Looking at the early 505 and the current MacBook Air, it seems pretty clear it's an evolution of the Sony design. I'm not saying there were no other subnotebooks, but it was the Sony models that steered everyone towards small, thin, light with optical drives. Toshiba and Fujitsu's first subnotes were rebadges of the Sonys, early on.
