What is more important when buying a Digital Camera-Megapixels or Optical Zoom?

I wanna know what to look for in buying a digital camera Mega-pixels or Optical Zoom or Digital Zoom?

Go for Optical zoom.
Mega pixels doesn't make a good photo. Good Optics does.

To make you understand a little bit better, a Point & Shoot digital camera has a sensor of the size 6x6mm (approx). As such when manufacturers cram in more & more megapixels, they are only helping to make the picture more noisier (more grains in photos). This is where DSLRs win hands down. For same megapixels, a large sensor will always perform better in terms of photo quality, colour reproduction, noise & dynamic range. This is because the pixels are bigger in the DSLR and hence have more capacity to collect data. As such the final product is far better.
