It's not bad Jim, I can just imagine lots of misguided people saying "How much" you have got a cracker, now buy a 30" monitor to go with it
If you have a suitable monitor you can attach it and it can be quite beneficial depending what you do.
The reason I said I hope you got it from John Lewis is that they give a minimum of 2 years and sometimes 3 years guarantee on Apple gear, they are a great Apple seller. I am sure you won't be disappointed. I advise you to download ClamXAV, it is a mac anti-virus and runs in the background and you won't know it is there unless there is a problem, under no circumstances get hold of norton or any of the other cons I mean anti-virus programs. I would also get hold of LittleSnitch it can block all attempts of different software to access the internet.
