->I'd only recommend USB for a Laptop. PCI is much easier to set up and works more reliable. You also get "more bang for the buck" with PCI cards, as USB cards tend to be a little bit overpriced. But if you're on a budget and need one card for both laptop and stationary machine (or if you hate screwdrivers), then USB is fine as well. It provides enough bandwidth for high quality stereo recordings.<- If you wanted to up the price a little bit, you could get something like an RME HDSP Multiface, or a related card, that would allow you to use the same unit with a PCI card in one machine and a cardbus on your laptop.
