Lego Mindstorms NXT 3.0 Kit

I think Lego has this fantastic product called Mindstorms NXT 3.0 which has all the elements to help you learn, program and build robots from scratch. Here's the link: #-Link-Snipped-#

I'm planning to buy one and wondering whether anyone here on CE has used it before. I'm not sure whether 3.0 version of Mindstorms NXT is available in all parts of the world. Please post your review and experience with it.
