It's true that many PCI soundcards have better capabilities than their 
USB counterparts. And at certain levels (multichannel in particular), 
the throughput exceeds USB 1.0 and you would need a USB 2.0 high-speed 
USB sound device to match that.

However, besides the obvious portability advantage of USB devices, there 
is one other interesting feature of USB audio, which is to isolate the 
A/D and D/A converters outside the generally noisy computer case, and 
this can provide higher audio quality than an internal PCI device. But 
only the higher-end USB devices would really have that advantage. I have 
used some low-end ones that were just as noisy as the first ISA 
Soundblaster 1.0 (Edirol UA-1A if you must know).
