Hi there! What's the 11inch MBA like with recording audio in Garageband? I am a guitarist and like recording lots of guitar overdubs on top of MIDI drum tracks. Obviously I'd also need to buy a USB interface as the MBA has no audio in. But will the new MBA be able to handle this? Will there be much latency? I currently use an 8GB Mac Mini (2011) and it is just fine, but I don't know how the MBA will fare in comparison. Any advice y'all can give would be great. Thank you!
