Hi, Just bought my MBP yesterday - first ever laptop so it's all new to me. I think i should get one or more USB sticks to back up documents etc that i create on the go. I also want to transfer my itunes from a desktop PC to the MBP (which i assume i can do using a USB?). Is there anything to get or avoid here? The chap in the Apple Store talked about some USBs not allowing the MBP to write to them but he used language that went over my head. I realise this is a very basic question.
