I'm perfectly happy to keep mine as a backup camera, but people who do a lot of low light photography don't like the A100 much because of the potential noise, but if the lighting is adequate (ambient or flash), it takes excellent photos.

High ISO noise was always the complaint from the beginning. But autofocus has also improved for the newer models. For more modest uses, it really isn't so bad. I used it at an indoor performance recently, with f4 to f5, and got good results. But a better camera would have been able to use higher ISO and gotten more keepers. Best results at higher ISO are had by using the RAW and running it through a computer-based RAW converter. Also, using lenses with wider apertures and using an external flash helps. I didn't realize how lame the internal flash can be until I compared it with the F42! What a difference!
What you lose at high ISO, you gain at low-ISO. I like the color and sharpness, and I find that the auto WB does a good job most of the time, although I use RAW often when the lighting is varied or weird (usually indoors).
But in the end, I'd only get an A100 today if it could be had at a very cheap price, and if it was because you were just price-conscious. If buying today, I'd lean towards an A500, personally; I could probably live without the few missing features considering all of the other advantages.
