The main issue raised is that I have purchased the laptop online. If there is a fault with the hardware (if it was software I think it would be identifiable and rectifiable remotely) then I would not expect to be asked to go in a retail shop especially when I do not live next to one.
Also, the level of activity in Apple shops has gone through the roof. Getting an appointment is usually several days after and if you just turn up you can wait for hours.
And then again, Apple has played a strange game with supply on this new product. Even if I was to go to an Apple shop, travel 2h return, wait 1h in the shop. What can they do, except telling me, sorry we do not have 1.3 rMB in stock, we will order the part required and you will have to come back in x days to waste a full day again...
So, I would expect Apple to say, we are sorry we missed a faulty item, we will send a replacement straight away and you can send your faulty computer back.
I think they have enough margins in their products to offer this level of customer service.
I am trying to do a clean re-install and then I will call the salesteam to request an exchange. Failing that it will be a return and a refund.
I am "lucky", the rMB is just a second computer for travel and that I have a rMBP so I can carry on working !
