portaudio is significantly easier to implement support for. this seems to
be the main reason it is used. i am working with another well known audio
software company and when faced with implementing windows support as part
of their own cross-platform efforts, they decided to use portaudio for
windows rather than try to code ASIO support directly (they had already
tamed coreaudio to their satisfaction). it must be possible, but apparently
aspects of it appear daunting.

in addition to ASIO, "modern" native windows APIs (WaveRT and WDM) are
capable of providing the same low latency path that ASIO does. i don't know
how many h/w makers actually provide drivers usable with these newer APIs,
though.
