My MBP is arriving tommorow . I'm going to buy an external harddrive tommorow and I was wondering if I'd need some speakers? I've been using a desktop with a monitor which has pretty loud built in speakers. I'm not sure if the MBP has these. I really like to blast my **** sometimes to feel the beat. I like listening to rap music but also watching movies and stuff... so suggestions on any speakers (if i need any)? I'm based in the UK so UK sites would be brilliant and I don't want to pay too much. This MBP was already expensive lol!
