And many camera's have higher noise, less detail, and lower resolution than the A100, yet cost much more (like the new Nikon D200) and people don't label them as "high noise".Quote:

This actually sounds more like Canon and Nikon fan-boys not wanting Sony to cut into their turf and show their precious camera up. So, they'll look for ANYTHING, even something slight like this so they can dismiss and label the camera something terrible, when it's not.
When I shoot, I typically only use ISO of AUTO or 100. At AUTO it will never shoot at ISO 1600. I couldn't get my A100 to shoot at ISO 800 either in AUTO (I believe the manual says it may select ISO 800 but it appears the margin for that is last resort). Maybe I'll try taking a picture in a totally dark room to test it. But basically, AUTO is ISO 100-400, which has "Canon-like noise" and those are the ISO settings most people use because they are the sharpest.
I would only use ISO 1600 under very rare situations, even with a Canon. And in those situations I may WANT noise! I remember back in the film days I would sometimes use ISO 3200 film because it was *SO* grainy. It was absolutely wonderful how noisy ISO 3200 film was, you could get some real rough and intense looking images with that much noise. The noise made the picture come alive! The point is, ultra-high ISO is not really designed for normal shooting, it's more designed for special situations, and in those situations you may actually want noise. If I wanted an extra stop, I'd go with a faster lens instead of going with a higher ISO.
Here's an example of that wonderful grainy Kodak T-MAX ISO 3200 film:
