The electronic accessories recognition and location feature is kind of cool, along with the streamlined data transfer techniques makes for a winner in my book. These things will be in hotels by christmas, expect to see them used WIDELY at the Beijing olympics (thats not from any official site, but I personally know two people from two totally separate companies both with contracts to develop content for retailers that will be sporting these come time for the Olympics.).
No, its not very far off in technology, but it seems put together very well. Just like the personal computer, the technology was already there, but the ones who put it all together are the ones who get all the credit.
