The DSC-W55 is a 7.2 megapixel camera with 56mb internal memory, 3X optical zoom, ISO up to 1000 and much more. It is affordable, ideal for everyday use and gives you high quality photographs. What I find very attractive about it is that you can get it in black as well as blue, pink and silver as opposed to most other digital cameras that only come in silver. This allows you to stand out from the rest of the crowd.
The memory is expandable, so even though you have 56mb to start with, (you can take about 60 photos at 2.0 megapixels, or 37 at 3.0 megapixels) you can easily expand it up to 4gb to meet your needs.
The battery life is outstanding and fully charged it will easily last for a weekend away or even a whole week if used properly. Charging it is very easy and only takes about 4-5 hours to complete. After a few years you can easily replace it at a low cost.
One downside to this camera is that you cannot add lenses to it to increase zooming and focusing abilities, which is why you are not paying the amount you would for an SLR. Although its auto focus is outstanding once you get to know how to use it.
One weakness that I have discovered from using it for almost a year now is that when you try to take a photo of a moving object it is relatively difficult not to get a blury image. Although there are some settings that help reduce this blur.
Overall, for personal use it is the ideal camera to carry around and take photos of your friends, your family, scenery, historical monuments etc.
