I have recently taken delivery of a new iMac (a few days ago) which I'm very happy with but today I became aware that a new model has just been released which has a better processor, much better graphics and (I think) better WiFi for only £50 more than I paid for the iMac I have just received. Thus it would have considerably more longevity. On my order page, it says I still have a little while to be able to return the device but I wanted to know if it's a "no quibble" policy. In other words, do I have to come up with some kind of "acceptable" reason or, if I tell Apple that the reason I want to return it is that a better model was released a couple of days later that I'd prefer to pay a little extra for (and so want to place a new order for), will they decline my return? Also, with regard to the return, I still have the while box that it arrived in with the polystyrene etc but I no longer have the screen protector plastic film. Is this an issue as far as returns go? Thanks in advance for any advice.
