Wow, I've never seen that video before. Pretty impressive amount of stuff that didn't make it in.
I guess this is the difference between Apple and Microsoft - Apple, by and large, doesn't show you the public until they're ready to sell it to you, at which point you see a near-finished beta.
Microsoft, on the other hand, tells you about their pie-in-the-sky dreams about what they're going to make, but just can't deliver.

Actually it's a pretty impressive amount of wishful thinking that never actually existed. Whether the producers knew it would never exist will be debated forever.
