Actually as far as I am aware (I don't actually own one) the US Interface
Navigator includes a sound card and a WinKey keyer. So you just need a
single USB connection to get full CAT control, PTT operation, sound card
functionality for data modes, and reliable high speed CW keying. Most of the
RigExpert interfaces are similar. It's handy if you want to keep your PC
sound card for normal PC uses, and it does reduce the usual rats nest of
cabling.
