My first MacBook turned up 4 weeks late, I was issued a £50 credit note. That was all well and good, until it turned a shade of green/pink/yellow. This was replaced for another C2D MacBook, which has a wobbly screen/doesnt stand up, and it changing colour (although not as bad). Apple told me it could only be exchanged for another white model, eventhough I wanted it exchanged for a black refurb to avoid the staining. The replacement arrived, and its a Core Duo, not a C2D - meaning its been swapped for an older model than originally purchased. I called them about this, and all the problems they'd caused - they told me I'd get the brand new Black one free of charge - great, progress. Today they called and said it couldn't be done and I'd have to settle for the CD I have, or have that exchanged for the C2D model. Is it worth all the hassle, to go from CD to C2D?
