Anyone bought this upgrade yet? I've just been stonkered by the Leopard guided tour and can't wait to upgrade. The ability to read through & preview most types of multi-page documents (page to page) without physically opening them is great. The Time Machine backup system is incredible - there is nothing else out there in Windows land that comes close to its usability and sheer elegance. This OS is going to be fabulous.
Can't wait to pick it up this week.
On a side note - I just bought one of the new Apple keyboards and a new 2-d scroll mouse for my Vista box. The best k/b and mouse I've ever used. They take a little getting used to but the low-profile "ceramic-feel" keys are terrific.
