I'd like to get a macbook pro to work with protools Le. I'd like to display 2 separate windows at the same time, edit and mixer. Will all of the macbooks pros, like maybe an older used one.... will they all drive 2 monitors? I don't need the newest one. I have a macbook but I assume it won't drive 2 monitors? I assume I would just need to buy an adapter to go out to 2 svga monitors? Thanks!
