What digital camera has the least amount of noise with the least amount of shutter delay?
I'm looking at the Canon PowerShot SD870 IS and the Sony Cyber-shot DSC-T70. I wish for it to have a very quick shutter speed with little delay, especially in indoor or dark situations. I've noticed that the Canon has quite a bit of delay in the dark, so is there any way to fix that? Also, I would like the camera to have little or no noise. Thanks.

In addition to Vienna's reference...
Digital SLR's have virtually no shutter lag at all.
If you pre-focus by pressing the shutter button half-way down while aiming at your subject - or where you anticipate your subject will be when you want to take the picture - it will help considerably. You can set your camera in "Sport" mode or "Scenery" and this will minimize the lag. If you do not use the flash, it will help. If you turn off "face detection," it will help. If you turn off the LCD monitor and use the viewfinder only, it will help. If you use the continuous shooting mode for a burst of 4 or 5 shots, there will be no pre-focus in between those shots. For most point and shoot cameras, this will give you 1.5-to-2 frames per second, but you can't use flash.
Some point and shoot cameras are better than others. I have a Canon Powershot SD900 that seems quite fast to me. If you go to http://www.dpreview.com and read the reviews (once they are available for the cameras you are considering), you can go to the page called "Performance" and see exactly what the tested shutter lag is, as well as several other performace benchmarks.
Here's a link showing a chart of various cameras and their shutter lag as well as the time it takes to shoot five frames. You will not see any DSLR's listed, because they have no shutter lag. If you click on the column heading, such as "One Shot," the chart will sort according to that measurement.

Delay - Most Common Guitar Effects
Another one of the most common guitar effects would be the delay. It is one of the most favorite guitar effects used by guitar players. It would also be often combined with an overdrive distortion or other guitar effects to achieve maximum results.
As the name implies, the delay would allow the sound to be played back at after a specific period of time. It can be played back several times or just one time into the recording.
Guitar players would use this effect to create some textures that over densely overlaid. The notes and the rhythms would then become complementary to the music. Some vocalists use a delay. It can also be used with other instruments to add some density or an ethereal quality into your playing. Delays that take about 10 seconds are used to create loops of an entire musical phrase.
The delay, as mentioned earlier, is one of the most used gadgets by guitar players. It has been used since the 70s and 80s and is still widely used today. However, the first digital delay that came with a pedal was the Boss DD-2. This was released in 1984. Some delay units are now rack mounted and are capable of incorporating other digital effects that are more sophisticated than pure delay like reverb and some audio time-scale pitch modification sound effects.
The more familiar digital delay systems normally function by sampling the input signal with a converter that would then turn the sound from analog to digital. The signal is then passed through a series of signal processors that then records it into a storage buffer. The play back is dependent on the parameters that you would set on the gadget. The wet or delayed output may also be incorporated with a raw and unmodified dry signal before or after it is sent to the digital-to-analog converter.
There are some digital delays that would offer other options. This includes controlling delayed signal's time before playback. Commonly, delays would also allow the user to set the overall level of the processed signal versus the unmodified one to be modified and to be repeated. Some more sophisticated systems offer an audio filter even.
