To be honest, I think you need to figure out what you will be doing with the pictures and where you will be taking the camera before we can give you some good suggestions... For instance:
Does size matter? Digital cameras range from the ultra small that can easily fit in your pocket (Canon Powershot S110, S230, S330, S400, Pentax Optio, Keyocera S4, etc) to the honkin' digital SLR's which you'll need to keep around your neck or in a hefty camera bag.... and everything in between. Think of WHERE you will have it most and if size would be a concern.
What are you going to do with the pictures? If it's pretty much for putting shots on the web or emailing to friends, you won't need more than 2MP (3MP at most). If money isn't that big of a deal and you think you'll be printing high quality 5x8's or larger, then 4 or 5MP might be justified.
Do you want a point and shoot camera or do manual settings matter? Do you need to control aperture and shutter speed or do you just want to turn the darn thing on and start shooting some nice pics? Manual features often (but not always) add to size and price.
