Surely this could be a case worth bringing to the attention of the UK Trading Standards authorities?
The UK Apple Store STILL has the graphic promising delivery on the evening of 24th. Regardless of what they actually MEANT by this, it states quite clearly that delivery would be on 24th, and it wasn't and was never going to be.
They're also just about the only online retailer who doesn't specify, or at least give some indication of, delivery times for their products. They do quote shipping times but those are pretty worthless - if your new iBook, for example, took 3 days to ship and 14 days to deliver, which figure is more important?
I'm sufficiently pee'd off with this to make an official complaint - anyone care to add their voice?
As for future orders from Apple Store UK? If they can't specify a delivery time (at least an approx' one), I'll take my business elsewhere, simple as that.
