I am really not trying to be snarky at all but have you looked through this forum before posting? There are several very informative threads addressing this very question on the first page alone.

And several others. If you could look through a few and come up with at least SOME idea of what you want and need, it would make helping you a lot easier. At this point, we don't even know if you want a DSLR or Point and Shoot and if you have any interest in furthering your photography or just interested in taking decent pictures with no extra effort. Any of those would be valid choices.
Help us a bit and we may be able to help you.
