Thanks for the feedback, I'd waited a while after posting this question before contacting apple, I was curious if it was a problem to anyone else. I didn't see many replies wherever i posted, so i did contact Apple, and they've arranged a replacement.
This is my first dealings with a company like Apple, i'm a switcher, always used BYO PC Clones.
I really like my Mac, i'm glad I switched, I hope my replacement is flawless!
Cheers
