Obviously I know this is not as powerful as a MacBook Pro, but how would it handle basic recording using Garage Band? I am in a band who is on the road constantly, and having a nice lightweight laptop would be nicer than a bulkier one. I'd use it for some Photoshop work and to record song ideas on the go. I'd get a USB powered interface to go with it. Just how bad would the performance be? I know it's a tad bit slower, but is it still usable for these tasks? Thanks for any help guys! BTW, I'd get the $1800 model.
