I have a studio about half an hour away from where I live with monitors and everything but I like to work on music at home in spare time...Because of this I will be buying a 15" MBP i5 or a 17" i7. I am not sure yet...anyways I am buying it because it is handy to take to the studio, plugin and to monitor what I have worked on....I do not really want to have to carry around another soundcard while working at home...Someone recommended the Apogee Duet but I do not need it really. I do not need any inputs ....only the output for headphones and the main out to plug into the monitors at the studio. I do not want to plug anything in if not needed.....is the stock sound card terrible? Will Logic 9 run the same on it?
