I have a MacBook that I use primarily for storing all my files/pictures/docs etc on, and use it for occasional music sequencing on GarageBand. I used to use Logic pro x but really didn't need all that power. I'd love to do the transition over to the iPad as my main 'computer' but have a question regarding the music side of things. Will I be able to import a music file in GarageBand from the iPad itself using the new 'finder' app? And using an SM58 Mic via a USB interface is simple? These are the only things that are holding me back from making the switch. Also I guess downloading files via an iPad from sites such as Mega Upload are still a no go?
