I think my Cannondale touring bike qualifies. Of course I've replaced 
consumable items like tires, chains, cogs, brake shoes, handlebar tape 
and occasionally a chainring. I've made some equipment substitutions 
(saddle, bar-end shifters, "aero" brake levers) but the original 
equipment is exceptionally durable.

For one example: The square taper cranks that Tom mocks still work 
perfectly well. I had to replace the original sealed bottom bracket one 
time, but there was no confusion about compatibility (and my cranks did 
not fall off!). The Stronglite roller bearing headset has also lasted 
decades, with one parts replacement. The SunTour rear derailleur is 
still perfect, although I did cheat a bit. When I powder coated our 
bikes, I traded my derailleur for my wife's, figuring hers had many 
fewer miles; but both still work just fine. Wheels are not original 
because I switched from 27" to 700C, but they're 20 years old.

I guess we'll see, eventually.

About that: A few years ago I got annoyed at the number of remotes. I'd 
read a good review about a programmable universal remote, and bought it. 
I followed the tedious instructions to program it so I could hit one 
button for "Watch TV", another button for "Play CD", another button for 
"Listen to radio" etc.

It's less than ideal. Part of the problem, I think, is that some of the 
devices use the same signal code as a toggle for "power-on" & 
"power-off", as opposed to a separate code for "On" and "Off." If a 
device is left in the wrong state, things don't work. There was also 
some dimly remembered problem where commands from the remote had to 
arrive at the TV at the proper instant - not too soon, not too late - 
and the program couldn't manage that, despite the nice lady at the 800 
help number trying over and over to cure. (I suppose I could dig back 
into the programming, but I'm not motivated.)

Your rooms must be much less messy than mine!

As I get older and older, I'm trying to get more comfortable with being 
an old guy who avoids mountains. Maybe some guy in a Frank Patterson
