For me? A lot! But, that's because I can't just go to a store
and *buy* most of them! E.g., if my hot water heater had a network
connection, then I wouldn't need to design and install something
to control it!
Ditto garage door opener, irrigation system, etc.
OTOH, if we could retroactively *credit* ourselves for devices we
wouldn't have purchased (i.e., assuming said system was already
in place), then the cost would be pretty modest.
Installation costs of a "real" system would probably rely on
wireless comms so you'd plug in a wall wart and forget about it.
(I don't want to address the security issues associated with
wireless -- given that I have so many other problems to tackle!)

No! The irrigation controller can operate in the absence of the
network and any "central controller". Ditto with the HVAC
(thermostat), etc. That's the beauty of putting *smarts* at
each node instead of just "field wiring".
Of course, you can't *change* the irrigation criteria if you
can't talk to the controller (over the LAN).

I think there will be a more in this direction RSN. There are
already firms touting "control your home from your iPhone"
(for only $60/month). When appliance manufacturers start
adopting integrated comms as a "standard feature", this will
get easier.
E.g., you see cars with iPod connections built in...
Currently, any attempt to do something like this requires a
"bolt on" product -- invariably more expensive than an integrated
solution!

What's far more likely to happen is a disk drive crashes and you
lose the media on the drive. The large drives that consumers would
typically purchase (incorrectly!) aren't intended for continuous
use.

Small. About 2000 sq ft. The real problem is that it is very
"open". No nooks to hide things in (unless we sacrificed a
bedroom). E.g., there is *one* small "coat closet" in the
"public" portion of the house. And that's got our coats,
vacuum cleaner and carpet cleaner hiding in it.
This is why I have given consideration to running HVAC into the
store room (presently part of the garage and, thus, non-living
space). It would be a great location for my servers, printers,
automation system, etc. (But, that means finding a place to
store the pinball machine, E-size plotter, potters wheel, etc.)

When it's 110+ outside, it's hard for the garage NOT to creep up!
(We were at or above 100F for the entire month of June and another
10 days into July)
Ours is reasonably cool with the insulated door (it also faces
east so avoids the afternoon sun shining on the door). Most
neighbors leave their garage doors cracked and/or leave the
"side door" that opens into the garage open (behind a security
door) for ventilation.

I've protected against that, here. But, "consumers" wouldn't
be as lucky -- since they would naively "enable updates" and.or
haphazzardly install all sorts of "free" cruft without concern
for *why* it's "free"! :>

They care only about how cheaply they can produce a home and
how quickly they can unload it.
And, most home *purchasers* aren't competent to evaluate the
shortcomings of a home. "Oh, look, Honey! There's a big tree

Agreed. I routinely go into a "panic" trying to identify things
to "get rid of". And, still there's too much! I swear the stuff

Sorry. I went through a similar experience recently. I recall
making the "calculations" as to whether I should seek care or
risk the weekend, etc. (here, dentists don't work on fridays
either! so, it's *three* days to reconsider your decision!)

Agreed. What happens when your device is "full"? Buy another?
Discard something to make room for a new addition?
I've just gone with PDF and EPUB formats and use a regular PC
(a tablet in this case) to view the documents. Not as pleasant
a reading experience as taking a book out to the back yard.
But, if it lets me discard a whole lot of paper...
Unfortunately, many of the titles just aren't available in
these formats. And, the idea of cutting the binding off
textbooks in order to scan their contents seems *sinful*!
