If you're looking for a trouble-free camera that is small, easy to hold, and convenient, there are a wide variety of cameras to choose from, including the Nikon S3 ($200-$350)
(etc) series, the Casio Exilim ($200-$400)
and the Sony Cybershot (Pink; $300-)
. I will say this: for hurried photographs, anti-shake is a very useful feature.
On the other hand, if you're looking to take unbelievable, photographic-quality pictures in RAW format, for just about $100 you can find yourself a Polaroid x530 with the foveon image sensor
