Nokia have said they estimate that most of the features will be production-ready in 7 years or so; they made a prototype to take to the MoMA exhibition, but I'm not sure how many features were ready to go at that point.
This is one chunk of the future that really can't come fast enough for me.
They did say it was only 7 years away from most of the features being production-ready, and that it'd be at the high-end initially. It'll be years more before a kid will get a Nokia like that for his birthday.
and yeah, will be maybe 20 years before this is a common product? by then we'll be getting all excited about the new implanted phones and the internet being connected directly to the brain...
