Looks like future PCs will have USB and Thunderbolt connectors.

When I rented a VW in Germany last year I was mighty disappointed that it had an automatic transmission. Maybe it was the edition for Amerikanskis. Anyhow, I could push the lever to the right and then had a whopping seven gears for hand-shifting. No clutch pedal though. To my real surprise it had a mph display in addittion to the km/h.

With film cameras dwindling away, would it be worth working up a mount for a decent 35mm zoom lens to a camera, so you could get some distance between the subject and camera lens?
Opinions here --->
I ran across this camera which is in a different housing then most. Says 5MP!
YOUTUBE video here.
Thoughts?

It already exists. I bought an Olympus E-PL1 plus a Fotodiox adapter that connects the existing collection of Minolta Rokkor lenses to this camera. Works nicely.
I don't have this one but if I needed to do some extreme macros I'd probably add this to the stack:
But you can't really us these cameras for soldering and things like that. Most don't have realtime output into a computer, have a voracious power appetite but no power supply connectors, and you don't really want to mess up such expensive lenses with solder fumes.

The Audi has a 6-speed dual-clutch automatic with no torque converter. It alternates odd and even gear trains and shifts in 60 milliseconds. It's my first automatic, but it's a lot easier to drive on the hills here than a manual, and Mo and The Brat can drive it, too.
The mechatronics package was replaced twice, and the transmission once, before the warranty ran out. I sure hope they got it right.

Those cars are very sporty, but it also means a lot of stuff is under high mechanical stress and gets busted easily.
That is not a good sign. I like to keep things simple, as in manual transmission. My big 1987 Audi station wagon is still traveling between Sweden and Germany, spoke to the new owners again a couple weeks ago (we are good friends). No serious repair bills, ever. Well, except when a delivery truck backed into it but that was paid for by their insurance.
I am also a strong believer that there should be the least amount of electronics in cars. Because electronics in cars break a lot, are usually grossly overpriced and designed non-repairable.

Nope.
I are not an optics expert, which entitles me to make a few expensive mistakes before I experienced what could have been better learned with some RTFM.
Mistake #1. I tried to adapter a 1/3" CMOS imager to various originally lenses designed for 35 mm cameras. These lens caused the image to overshoot the usable area of the CMOS imager. The result was substantial magnification of the center part of the image, but with a loss of about 80% of the light. The same lesson was repeater by purchasing a microscope tube CMOS camera, without the necessary 0.5x optics. I obtained some center magnification, but at the expense of brightness.
Mistake #2. More pixels in the same image area are not necessarily better. You'll get better resolution, but because the pixels are smaller on the imager, they will be less bright. The CMOS imager responds to insufficient lighting by adding "noise" to the image, which is often worse than not having enough resolution.
If you look at the lens diameter (not the barrel diameter) of a DSLR camera, you'll find a much smaller lens than on a 35mm camera. The effect is to get the f-number (focal-length / Lens_diameter) as high as possible in order to get decent depth of field. Microscope objective lenses are another example, where the high power lenses tend to be very small diameter. If you want depth of field with a microscope, it takes a large f-number (small dia lens), and lots of light.
Where? I don't see any opinions.
- Only useful for flat objects.
- Autofocus has never worked well for me.
- No way to lock it into position. At 200x, things move.
- Can't get close enough to a PCB to inspect solder joints.

1/3" is really puny. But try this with four-thirds or micro four-thirds cameras. I did, and the new Olympus E-PL1 with the 35mm Minolta Rokkor lenses from the 80's makes stunning photos. I didn't even buy any Olympus lenses with it.
True, but compared to ye olde grainy 400-ASA slide film even some middle-class cameras are better.

It was all I had handy, borrowed out of a Logitech USB camera.
Yep. 4/3" sensor at 18.5mm x 18.0mm are getting close to the original
24mm x 36mm film image size. This drastically reduces the loss of light and center magnification problem caused by small imagers. It should work nicely with 35mm type lenses. However, trying that with my Canon S5IS camera, which as a 1/2.5" sensor (5.7mm x 4.3mm), is not going to work so well.Ugh. That brings back nightmares of evenings in the darkroom. Yeah, Tri-X was really grainy. I still have boxes of prints and film rolls from those days. Polaroid 107 prints were much better and easier, but the cameras were a PITA to adapt to a microscope.

Well, a USB camera is indeed the lower end of photography :-)
With my Olympus it leads to roughly 2x more focal length. So a 250mm tele lens is now like 500mm. Which is great but at the other end it's a bit of an issue because the lowest focal length I have is 28mm which now equates to 56mm. Meaning I've no longer got a wide angle lens which might be the reason I'll have to buy an Olympus lens (or another older Rokkor) some day.
It was amazing. When I put on that tele lens after unpacking the camera I held it out in the distance, focused and took my first shot. A tiny whitish splotch that I could barely see with my eyes was quite visible now. Zoomed up ... and could see read the text including a telephone number on there. Scary.
I ruined several shirts with this instant film stuff back in the 80's.

My truck has two "Cigarette lighters" (one is an unswitched AUX port). My wife got an "octopus" for her lighter (that didn't come with one) because of all of the devices she uses.
USB connectors are, or at least shortly will be, ubiquitous in car audio systems. Some are remote, in the console but some are in the "radio" itself. 2A capability for iPads, even. The iGods have spoken.

How about their new iBacon from their iSwine divison?
little as $1.

Maybe, a bit too oddball and not enough better than USB 3.
?-)
That's what I'm trying to figure out. But thanks for the pointer! (Though I'm yet to find out where I could buy it at that price, /delivery included./)
The cheaper models (say, < $50.) But if there're specifications for the other models (that I might have missed) -- I'd gladly check them out.
