There are also some other limitations as well. i find that when I start to do projects that involve lots of tracks, for example I am working on one right now with 3 recorded guitar tracks and 11 other midi tracks, that the 10v crashes quite often during playback. I guess the limited processing power of the 10v cannot handle the load. Though it makes sense considering the specs of the average new mac that garage band was designed to run on, its no surprise that it struggles with larger projects. My nephew uses a USB condenser mic with garage band all the time and has great success, but that is with his mac book pro. After using my daughters usb high school musical mic with good success, I ended up buying a boom style mic stand with a universal mic shock mount and a pop filter. Seems like a great basic setup that I can position to record in front of my various amps, or for vocals. I went to school for audio engineering and have had lots of past experiences working with studio grade mics at various studios in town, so I was really surprised at how clean the cheap USB mic sounded, and thats is why I have stuck to using it so far. I will probably end up buying a USB confessor mic in the future though to supplement it.
