Haha yes thank you - I learned the hard way
You were pretty spot on though! Shipping estimate was for Tuesday but once it reached UPS in Tamworth it fell back to Monday, so woop for tomorrow!
Also I had a question so I can avoid further disappointment and waiting - when you get some new phones/laptops etc, they advise not to use the product for 24~ hours, you should just charge it.
I know that's not mandatory ANYWAY, but I'd prefer to do everything by the book with this laptop, etc. Is this one of *those* laptops?
No, not for lithium-ion batteries (i.e the one in your rMBP). I always let it charge to full before switching on. I think I read on Apple's website they recommend that, too.
