It's very easy to desire a new camera. Since it is near Christmas, camera manufacturers and camera retailers have significantly increased their advertisement campaigns. It's easy to get caught up in wanting the latest digital camera.
Cameras are tools that photographers use to create photographs. Cameras are like household tools--cordless power drills, skill saws, electric sanders, etc., make the work easier, but for the vast majority of jobs all one needs is a screwdriver, hand saw, and a couple sheets of sandpaper. For most household chores, those power tools are overkill and unnecessary. But they are still nice to have for when you do need them.
It's similar with cameras. You don't need the Leica M9, Fuji X100, Canon EOS 5D Mark II, or Nikon D3X. Those cameras might make what you are trying to accomplish easier, sometimes much easier. But there are other tools available that will get the job done. Any camera in the hands of a skilled photographer can be used to create a masterpiece photograph.
Having one of those cameras mentioned above won't make one a better photographer, and not having one does not mean one is any less of a photographer. If you have the extra money lying around and you desire to purchase a $7,000 camera, then go for it. It's completely unnecessary, but it is nice. If you don't have the extra money, don't fret! The camera you already own is capable of creating works of art and award-winning images.
It's much better to spend your time, money and energy learning how to craft great photographs than on a new tool that you don't really need. At the same time, there is nothing wrong with having nice things to make your job just a little easier.
