See Snow Crash by Neal Stephenson or Steel Beach by John Varley. Another one, which I think is more likely, is The Gentle Seduction by Marc Stiegler. It's also more hopeful.

Let's just say that I expect to be able to get an implanted cell (or whatever) phone before I die, as well as a clock, access to consensual reality, and other things I've not yet thought of.

Go to work? Why bother? It's right here (thinks) and, Oh, you're up for a game of Unreal Tournament 2050? Let's play! No disks, no desktop equipment, or very little. Modems? They stopped making those 40 years ago!

Power? Not a problem. No one wanted to implant nasty chemicles inside themselves, so we found a way to power these things by having them metabolise body fat (or blood sugar, or whatever). Hey, it's my fucking concept, so I'll make it come out as I want it to. I'm a lier; the idea isn't mine. Saw it in a science fiction magazine more than 10 years ago.
