I was in the EXACT same boat as you. I looked at the M-Audio stuff, the Presonus Firebox, and the Ediro FA-66. I landed on the E-Mu 0404 USB. I like the idea of it being USB because apple is dropping FW on their models slowly but surely. Future proof, and gives me a greater choice in laptops during my next purchace, I won't be forced, or limited to only the "Pro". USB is perfectly fine for recording its max of 4 tracks at a time. It IS USB 2.0 watch out for others that are USB 1.1 like the edirol UA-25 if it doesn't specifically say it is 2.0 it's not.
