I preordered it a month ago and I received it today. After a fresh OSX leopard install it boots in five seconds!!! Photoshops opens instanctly, and everythings goes like in real time, no lags anymore!! And the best is that with my 17" 2,3GHZ i7 macbook pro it prolongs battery life up to 10 hours in web browsing!! I have noticed that it has no problems with hibernation. So it works just PERFECT!! This is amazing!!
