Even if you cut out a whopping let say 50% of your original photo,you've still got an image wit 6 megapixels which is more than enough to make a nice 11x14 or 8x10 printing if you desire so.
More Space,More Power
12 megapixel photos take up a lot of "digital space" which require:
.Larger hard drives for more than permanent storage
.More powerful computers to view and edit
.Larger memory cards when the photo is taken
While you might having a fantastic time taking photos with the camera,then you try to view them on a five year old computer with a relatively small hard drive the results will be less than satisfying.Make sure you've got a nice high-end computer and plenty of clear space on the hard drives FIRST (or better yet,a dedicated external hard drive for photos) and then get yourself the 12 megapixel digital SLR of your dreams.Here are few examples of latest 12 megapixel camera models:
