Megapixcel Competition

In past days the megapixcel ranges of still cameras have range from 30 to 40 (megapixcel). This heavy expansion for taking closest images have kept this industry on fast track and industry competitors seems create boom in the market. So there is a full and complete marketing going on in the industry by competitors.
In my personal opinion, the digital camera industry is making a slogan “Innovation and Attraction”. The word “global village” seems a small word but it means a lot. The shrinking of world has created opportunities for many digital camera’s companies to explore new markets and take advantage of resources through out the world.

Many companies are throwing the digital camera’s megapixcel technology widely in mobile devices. I wonder that if one day people loose their interest in digital camera (still and video).

So the questions in my mind arises are;
1. Digital Camera (still and video) can be replaced by mobiles?
2. Do you think that it’s a burden to carry on the mobiles, still and video cameras separately?
