Hey everyone, first post! I thought I'd share my order status, it if helps any of you guys...
I ordered my 2.0 glassbook, with sleeve and ipod nano (all with university discount) at midday on Wednesday 15th. It shipped this Wednesday (the 22nd), and I received the confirmation email at about 11:00 on that morning. I don't have any tracking details yet, although I do have a new delivery estimate of October 31st (next Friday).
I read somewhere that if one just orders a pre-configured mac, with no accessories or anything else in the order, then UPS handles it all the way from China to your UK address (which might explain why some people already have UPS listed as a carrier).
However, if your mac is not the only thing in the order, then it's shipped to Apple's European distribution centre in the Netherlands, where it is re-packed with the rest of your order and handed over to the carrier that will deliver it to your UK address (and it is at that point that you are given a tracking number).
Apparently Apple UK's base in Cork might see the mac at some point as well, but this doesn't fit in to my delivery chain hypothesis so I'm ignoring it
I could be wrong about all of this, but it's just the information that I've managed to glean whilst waiting for my fabled macbook.
