The audio quality of the built-in I/O on any computer is questionable, but high-fidelity is not always the first priority. Personally I like great sound quality but regardless, built-in audio is only stereo and I like quad or 5.1. So I'm stuck with a card for now. However the newest Magma expansion chassis works with Pismo powerbooks, works with the MOTU PCI-32 card (providing a mere 7 msec latency) and is not much bigger than the laptop itself, so it can all fit in a carry-on bag. I've used a VX Pocket live but only a few times. We had trouble with the breakout cable. The CPU overhead was not 30 percent, but it was a hit. The latency problem is a big one but for looping, it can be compensated IF the OS provides a constant latency. I have a latency-compensating looper which I am diligently refining into share-able condition. By the way, when was the last time you measured the latency of your outboard rack? -Alex S.
