This week a piece of technology was reviewed on the site that I think is one of the most 
significant releases of the past few months – the Sony Ericsson K800i. The reason I think it’s so important is because of its 3.2 megapixel camera.
At this level of resolution the quality level is such that the average person now has the ability to take ‘proper’ pictures - images of sufficient quality that you’ll want to keep them, print them and share them. Of course, image quality is not all about resolution, but the K800i has that covered with some decent optics, and features such as image stabilisation and a flash.
Camera phones are certainly no longer the novelty that they once were. Two megapixel cameras have been standard for a while and cameras such as the Sony Ericsson K750i are capable of quite decent images. For a long while my main camera was the original Digital Ixus, which only had a resolution of 2.1 megapixels and that was good enough for me to print up to 6 x 4in.
If that was the case, having 3.2 megapixels in the phones in everyone’s pockets could potentially put a real dent in the sales of compact cameras such as the Canon Ixus. If a phone only has a 1.3 megapixel CCD then there’s still a good case for shelling out on a four or five megapixel camera. TrustedReviews - The Hunt for the Perfect Mobile
