$20 of CAT5, $10 of jacks, and a $20 fish-tape isn't fiscally feasible, but these gizmos are?
If we are talking about standard residential construction, don't forget the few hundred in wall repair costs.
Either you haven't done this very often, or when you have you haven't done it very well. Even in the simple example you give - room over a room - you can't just run a fish tape down the wall to the other room (unless it is balloon framing which just isn't that common). There are sill and top plates and probably blocking that you have to drill through first. There are some really cool, really long flexible drill bits that you can actually fish through a wall, but that is only going to work sometimes.
Normally what you are going to have to do is cut open the wall near the obstructions so that you can get a drill in there to drill through them.
Then if you have to go across a wall, open it up to drill through studs. Or going from wall to floor cavities, open it up to drill through the plates and get around the corner (unless you have a magical fish tape that can navigate around corners without having to try a couple thousand times). Or if the construction is brick or concrete, no fishing at all.
If it were so easy to fish wires through walls, there wouldn't be so much dangerous old wiring in houses.
Small offices in standard office construction are another matter. They usually have ceiling plenums that provide horizontal running routes and access to the top plates of the walls, if the walls even *have* top plates. So I see no reason why someone wouldn't want to just wire it up in that case.
With the right upgrades, the 9600 runs OS X great. I loaded one up with a G4, 512 MB ram (the thing will go to 1.5 GB) and an IDE card and drive and it runs 10.3 great. It also has firewire, USB, and upgraded (but not Quartz Extreme compatible) video card, 100BaseT.. overall a handy machine.
So, my 8 year-old machine runs the latest OS well.
