Not very good.
Bob forgets one crucial thing: you'll still want a big screen (when you're not travelling). The screen is immobile most of the time, so the PC doesn't have to move either.
Don't expect futuristic implants in any forseable time.
This screen may be a future high resolution TV instead of a "monitor", but there would basicly no difference anyway. It's a big screen; you don't carry it with you.
The PC itself may even become smaller, but that doesn't make the old tower any less viable.
And finally when you do want to take a device with you: if the hardware is advanced enough and it runs Windows, it basicly is a PC.
Laptops ARE PCs, something even smaller can also be a PC.
