I know much less about this than I would like, but I have the feeling that
the StrongARM and Dragonball have very little market in Japan. Hitachi comes
up again and again as a processor commonly used, but does anyone know of
others? Tony, either your focus on US (althought the StrongARM was developed
in England, it is now owned by Intel) component makers is misleading when
talking about the Japanese handset market, or the Japanese have done a
pretty good job at covering the tracks of origin. I have a StrongARM, but
that is in my Newton (don't laugh, it is a pretty f***ing good PDA as far as
speed and capabilities go, and I still use it as a convenient typing tool,
as well as dictionary and address book). Anyone know any more about what
Japanese handsets are using as processors than either Tony or I do?
