I can't wait for bioelectronic implants.
The thought of a usb husb in my forearm, leading to a 3G modem in my chest cavity, fills me with excited anticipation not unlike the week leading up to Christmas.

Will there be a big divide between Mac and Widows type people? The non-customizable, sleek looking Apple-based cyborgs, vs the more haphazard but upgradable Windows-model humans?
And then of course you'd have the Linux-fringe lunatic walking around with exposed wiring, rewriting the applications which regulate bodily functions for maximum efficiency.

Gah, hurry up!
