As for prices in the UK, they start at £749 (including VAT) for the basic model (1.83 GHz, 60 GB hard drive, and a CD-RW drive), and then increase to £899 for the next model up (2.0 GHz and a SuperDrive). The black model starts at £1028.99, but has an 80 GB hard drive, in addition to the features of the mid-range MacBook.
The bottom and mid-range versions ship in 3-5 days here, and the black model (top of the range) will take 5-7 days. Bluetooth and Airport Extreme seems to be built-in, and the models use the scrolling trackpad. I also notice the MacBook includes a Firewire 400 port, which is good, as I started to wonder if Apple was dropping Firewire...
