I'm looking to get a new haswell 15" rMBP when it comes out, hopefully at the October 22nd event. I'm in the UK and can use a student discount, making AppleCare £220 for the machine. What are the real benefits of AppleCare, what kind of service will I get from apple without it and any ideas on whether I have to purchase it at the same time as the computer or can wait a month or two down the line when I've got a bit more cash? Thanks in advance
