I have a couple of radios from 1925 that are very simple machines of wood, metal, bakelite, and glass, yet they perform quite well by any standards. They are so simple that they are just about bullet proof. The trend toward small, cheap, and efficient electronics often produces devices that don't even get close to the quality of the old simple ones.
Blasty hit the nail on the head with that one. Unfortunately, that's the way everything is going these days. The old idea, making quality products that were built to last, has been overwhelmed by a new one: make inexpensive and cheaply made products, and promote a high turnover rate. Two classic examples of that today are cell phones and (I'll more than likely get flamed for this) the Apple iPod.
I had noticed this before (especially the way cell phones have changed in seven years - compare my uncle's Sanyo SCP-3000 with the modern crap on the market) but had never had more it in my face than when I repaired our 1960s-1970s garage door opener.
Our best guess is the thing, a Monarch Electric Garage Door Operator, is about 40 years old. It's the style with a belt on the bottom driving a chain on top. So when it failed just after last Christmas, all it took was replacing the $5 switch that rides the control cam (yes, this thing is controlled mechanically, even the auto-reverse! There's not an IC in it, aside from the Linear Delta3 radio controller that was added.) It was an easy repair too: the control cam assembly could be removed and easily serviced. Best yet, the unit is made almost completely of metal. That thing could likely go at least another 40 years with subtle repairs like this.
Something else that gets me these days are the "maintenence-free" designs that are indeed maintenence-free - until you have to replace the entire unit! Newer openers don't have that belt that may need to be swapped, they use cheap plastic gears instead. I tried to repair a friend's jammed 1995 Chamberlin machine - with no luck! His father had a similar experience and trashed the thing. So compared to that, is it really that hard to swap the drive belt? Is it that time-consuming? Is it that expensive?
The same goes for sirens. A Cold War-era siren may require periodic maintenence, but will be very reliable if kept in shape. Simplicity is a big factor too, and I'll refer to a common phrase in the aviation industry: "A part that is not present cannot fail." While new features, such as battery backup and self-monitoring capabilities, can greatly enhance the effectiveness of modern sirens, some, particularly electronic sirens, are awfully complex, and a single component failure can take out the whole system - an ATI with good drivers but bad amplifier finals won't be of much use.
