Not to thread hi-jack but does anyone know of a good (inexpensive) USB 2.0 card? I just got my Nano and realized I only have 1.1 (my computer is 4yrs old). The manual recommends getting a 2.0 card if you don't already have it on your computer. I don't even know what the hell this is and you guys seem to know a lot more about computers than I do.
