What do you think of this camera? Should I get it?

This would be a good buy, but you might not have noticed that it is out of stock on the website you gave. That being said, Vivitar is a good brand, the 5mp is a good compromise for an inexpensive camera, and its other features are good on the same basis. If you go beyond 2X or 3X on the digital zoom, your photos will start to look grainy, so watch that. That's because a digital zoom just magnifies the central part of the photo, it doesn't re-focus the lens. You should be able to get about 100 photos on a 256mb SD card - it might be worthwhile getting a 512mb or even a 1gb card.
