To echo GlueGuys remarks...
Do not be seduced by a cameras pixel count. I supposed manufacturers use pixel count because it's easy to quantify just as tractor manufacturers use horsepower ratings. There's so much more that goes into getting a good picture. For first time digital camera buyers my advice is, absent a specific intended use, e.g., sports, wildlife, which can imply the need for specific features.
1. Buy an inexpensive digital camera. It almost doesn't matter what brand or kind or what features it has. All the major brands will be able to take a good picture.
2. Use the camera. /w3tcompact/icons/smile.gif This is kind of obvious, but some people only take pictures at birthdays and holidays which really isn't enough opportunity to get to know what you like and dont like. Take indoor pictures, outdoor pictures, action pictures, stills.
3. In addition to not being seduced by pixel count, also determine which features can be duplicated in software, e.g., sepia tone.
4. Once you've used a camera for a while you will be in a much better position, assuming you've kept track of your likes and dislikes, for purchasing your second digital camera (yes, there will be a second camera for most of us!).
Some other observations;
Distant wildlife - High optical zoom
High optical zoom - Image stabilization or the use of a monopod/tripod
Stop action - fast shutter speed and buffering of pictures
Low light - High ASA speed (800 and above), image stabilization, monopod/tripod
Lots of flash photo - Good battery life and recovery of battery/flash
