My guess is that it will be a Bluetooth screen that you wear like a pair of sunglasses that can hook you up to the internet.

That really seems impractical. I mean, the person would need to be sitting down or something. They certainly couldn't drive, or ride a bike, or walk about. They could hit a tree while checking their email, or get hit by a car while looking at porn. But it sounds neat.

My prediction is that cell phones will actually evolve into tiny devices that are planted into one's brain. One second a guy is sitting quietly on the subway, the next he's laughing and saying things like, "Naw, naw man, she didn't.." Then all the other passengers will look at each other and smile. "Got a call on his brain phone", they'll say.

You could adjust the darkness/transparency level of the sunglass screen. For driving, you would want completely transparent. For walking partially transparent so you could also see the Web. For sitting, completely opaque so you see only the Web.
