Seems counter-intuitive. In the old days, film was the most replaceable part of your camera system, and lenses were (usually) the least. I believe this holds true today, with most lenses outliving the sensors (using a broad definition of "outliving" to include general usefulness to the photographer), and in fact most bodies working well and fine even once you've determined it time to upgrade the sensor again.

Why not just have bodies, sensors, AND lenses inter-replaceable? This system seems more limiting than what we've already got...

I went to MSU- go green! They have a history of odd robotic creations.

They're working on it, but it doesn't seem to be working so well so far:

I too love NPR- no commercials every 5 seconds and generally good programming. If I want music I've got my own, if I want anything else I've got NPR. Course I didn't start liking NPR till I moved to Ann Arbor... must be something in the water here.

Now just add wi-fi and I'll be happy.

At some point this long-lasting light bulb idea fails to make economic or even practical sense. The longer a light bulb lasts, the more likely it is to succumb to "accidental trauma" like brooms or flying children and break before its time had come. Also, the more likely that the inhabitants of the building the light bulb is in will move on- at 19 years even homeowners are often moving out or dying, leaving the "cost savings" of the bulb to be passed on to the next inhabitant unless they carefully pack up all their light bulbs with them when they move. Finally, over 19 years there are definitely going to be changes in lighting and maybe even how we power our homes- you may be stuck with an antiquated "energy efficient" light bulb that just won't die and that you need to run a generator to power because everyone else has moved on to luminescent fusion-powered floating sentient mini-clouds.

I'm sure that it's safer than it sounds, but you'd think attaching a foreign device straight to the bone that also happens to surround a particularly important organ in a man who has chronic ear infections with bugs now resistant to most antibiotics would be asking for trouble...

Why? The thought was that they were much more efficient. Or would you not be surprised by the headline:

"Study says electric cars are about as efficient as SUVs"
