Apple MacBook Pro Thunderbolt

It's that time of year again: Apple's busy upgrading their desktops and laptops, starting with the new Apple MacBook Pro Thunderbolt ($1,200-$2,500). Available in 13-, 15-, and 17-inch varieties, these new laptops feature dual- or quad-core Intel Core i5 or i7 processors, plenty of RAM, FaceTime HD webcams, AMD Radeon HD graphics processors with up to 1GB of video memory, and the unibody aluminum enclosure we've come to know and love. New this time around is Thunderbolt I/O technology, developed by Intel, which provides a replacement for all sorts of ports while promising transfer speeds of up to 10Gbps. Wasn't there an AC/DC song about that?
