Having owned quite a few cameras for work and for home, I think there are a few ways to find the camera you want. Look within your budget range and pay attention to the megapixels, as Lexx said. Then see if you can try out the camera in store. It may suprise you, but some cameras take better looking photos than others, regardless of megapixels or listed functions. Some just seem to capture better hues automatically, and you want one with great hues if at all possible. Another way is to test drive family and friend's cameras, or look at photos they have taken with them.
You need a certain base amount of megapixels to produce photos for print resolution (aim for A4 or A3 size finals at 300dpi) so decide this if it is what you need it for.
I find cameras perform differently for different weather or indoor/outdoor, no matter what their buttons say. My Nikon performs well with product shots indoor and outdoor and on sunny days, whereas my Canon works best outside on overcast days. I prefer using the auto function instead of playing around with shutter speeds and ISO for every single photo.
Recommendations from others are a good way to find out useful brands to explore.
