Hello, I'm looking to pick up Logic Studio, and a portable to run it. I'll be using Logic mainly as a composition tool-- software intstruments, printing sheet music, etc... I'll also likely do some demo recording, but one or two mics-- no multitrack setups. Trying to decide the best route to go-- Macbook or Macbook Pro. My understanding is that the main difference will be in screen real estate and in peripheral hookups-- that the processors should be a wash. Financially, it'll be a little tough to get the Pro. However, if it really is that much better than the Macbook, I can make it work. Any thoughts?
